Complete the Decimal Sequence: 0.5, 0.6, 0.7, Finding the Next Three Terms

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

• Step 1: Identify the pattern in the given sequence.
• Step 2: Continue the pattern to find the missing terms.

Now, let's work through each step:

Step 1: Look at the given sequence: $0.5, 0.6, 0.7$. We notice that each term increases by $0.1$.

Step 2: To continue the pattern, add $0.1$ to the last given term, $0.7$:

• Next term: $0.7 + 0.1 = 0.8$
• Next term after $0.8$: $0.8 + 0.1 = 0.9$
• Final term to find: $0.9 + 0.1 = 1.0$

Therefore, the complete sequence is: $0.5, 0.6, 0.7, 0.8, 0.9, 1$.

We can verify this matches choice number 1 in the provided answers:

$0.8, 0.9, 1$.
