Consecutive Numbers up to 10,000: Fill-in the predecessor and the successor in the series

To solve this problem, we will determine the predecessor and successor of the number 9001 by using simple arithmetic operations.

• Step 1: Calculate the predecessor of 9001.
• Step 2: Calculate the successor of 9001.

Now, let's work through each step:

Step 1: Calculate the predecessor of 9001. The predecessor of a number is found by subtracting 1 from the number. Therefore,

$9001 - 1 = 9000$.

Step 2: Calculate the successor of 9001. The successor of a number is found by adding 1 to the number. Therefore,

$9001 + 1 = 9002$.

Thus, the predecessor and successor of 9001 are $9000$ and $9002$, respectively. Therefore, in the given format, the answer is:

$9000,9001,9002$.

Matching this with the provided choices, the correct choice is:

$9000,9002$

To solve this problem, we first need to determine the predecessor of 2000. The predecessor is found by subtracting 1 from the number:

• Predecessor: $2000 - 1 = 1999$

Next, we find the successor of 2000. The successor is calculated by adding 1 to the number:

• Successor: $2000 + 1 = 2001$

Thus, the predecessor of 2000 is 1999, and the successor is 2001.

Therefore, the sequence with the number 2000 and its consecutive neighbors is given by:

$1999,2000,2001$

Comparing this with the provided choices, we can confirm that the correct choice is : $1999,2001$.

To solve this problem, we need to determine the numbers directly before and after 3001 in a consecutive integer series.

Let's follow these steps:

• Step 1: Find the predecessor of 3001.
• Step 2: Find the successor of 3001.

Step 1: To find the predecessor, we subtract 1 from 3001:

$3001 - 1 = 3000$

Step 2: To find the successor, we add 1 to 3001:

$3001 + 1 = 3002$

Therefore, the missing numbers that precede and succeed 3001 consecutively are $3000$ and $3002$, respectively.

The correct answer is choice 1: $3000, 3002$.

To solve this problem, let's methodically follow these steps:

• Step 1: Identify the predecessor of 4400.
  To find the predecessor, subtract 1 from 4400:
  $4400 - 1 = 4399$
• Step 2: Identify the successor of 4400.
  To find the successor, add 1 to 4400:
  $4400 + 1 = 4401$

Having followed these steps, we can conclude that the numbers we are looking for are $4399$ and $4401$.

Thus, the solution to the problem is $4399, 4401$.

To solve this problem, we'll identify the consecutive numbers surrounding 5019. Specifically, we're looking for the predecessor and the successor.

• Step 1: Find the predecessor of 5019.
• Step 2: Find the successor of 5019.

Now, let's work through each step:

Step 1: The predecessor of a number is 1 less than the number itself. So, the predecessor of 5019 is $5019 - 1 = 5018$.

Step 2: The successor of a number is 1 more than the number itself. Thus, the successor of 5019 is $5019 + 1 = 5020$.

Thus, the missing numbers are 5018 and 5020. Therefore, the sequence is $5018, 5019, 5020$.

By comparing these numbers with the provided choices, we find that option 2, $5018, 5020$, is correct.

The solution to the problem is $5018,5020$.

To solve this problem, we need to find the numbers just before and after 6000. This involves simple arithmetic calculations.

• Finding the Predecessor:
  The predecessor is the number before 6000. To find it, we subtract 1 from 6000:
  $\text{Predecessor} = 6000 - 1 = 5999$.
• Finding the Successor:
  The successor is the number after 6000. To find it, we add 1 to 6000:
  $\text{Successor} = 6000 + 1 = 6001$.

Thus, the complete sequence is $5999, 6000, 6001$.

Now, we compare this result to the provided choices. Our calculations match the correct choice:

The correct answer to the problem is: $5999,6001$.

The task is to identify the predecessor and successor of the number 9899 in a sequence of natural numbers.

Step 1: Determine the Predecessor
To find the predecessor of 9899, calculate:

• $9899 - 1 = 9898$

Therefore, the predecessor is 9898.

Step 2: Determine the Successor
To find the successor of 9899, calculate:

• $9899 + 1 = 9900$

Therefore, the successor is 9900.

After determining the predecessor and successor, we find:

• Predecessor: 9898
• Successor: 9900

The correct choice based on the calculations provided is:

$9898,9900$

Therefore, the sequence is complete as: 9898, 9899, 9900.

Let's solve the problem following these steps:

• Step 1: Identify the given information: We have a number 8500 and an indication of a sequence: $\Box, 8500, \Box$.
• Step 2: Find the predecessor: Using the formula for the predecessor of a number, calculate $8500 - 1 = 8499$.
• Step 3: Find the successor: Using the formula for the successor of a number, calculate $8500 + 1 = 8501$.

By computing these values, we find the missing numbers in the sequence as 8499 and 8501. Therefore, the sequence is: $8499, 8500, 8501$.

The correct choice from the provided multiple-choice answers is: $8499,8501$.

To solve this problem, we will determine the predecessor and successor of the number 7190.

• Step 1: Identify the given number, which is 7190.
• Step 2: Calculate the predecessor by performing the operation $7190 - 1$:

When we subtract one, we get $7189$. Thus, 7189 is the predecessor.

• Step 3: Calculate the successor by performing the operation $7190 + 1$:

When we add one, we get $7192$. Thus, 7192 is the successor.

We have determined that the numbers are:

$7189,7190,7192$

Therefore, the missing numbers are $7189,7192$.

To solve this problem, we'll follow these steps:

• Step 1: Identify the number provided in the sequence, which is 6700.
• Step 2: Determine the predecessor of the number 6700.
• Step 3: Determine the successor of the number 6700.

Now, let's work through each step:

Step 1: The number given in the sequence is 6700.

Step 2: The predecessor of 6700 is found by subtracting 1:
$6700 - 1 = 6699$.

Step 3: The successor of 6700 is found by adding 1:
$6700 + 1 = 6701$.

Therefore, the consecutive sequence around the number 6700 is $6699, 6700, 6701$.

The correct sequence with the missing values filled in is: $6699, 6701$.

To solve this problem, let's determine the consecutive numbers surrounding 84100:

• Step 1: Identify the existing number given, which is 84100.
• Step 2: To find the predecessor, subtract 1 from 84100: $84100 - 1 = 84099$.
• Step 3: To find the successor, add 1 to 84100: $84100 + 1 = 84101$.

The number that comes before 84100 is 84099, and the number that comes after 84100 is 84101. Therefore, the sequence including the given number is:

$84099, 84100, 84101$

Therefore, the correct answer is: $84099, 84101$, which corresponds to choice id="4".
