Consecutive numbers

A consecutive number is a number that is greater by 1 than the existing number.
When we are asked -
The consecutive number of "any number" is...
We calculate as follows: Any Number+1Any~Number+1

When we are asked -
"Some number" is the consecutive number of...
We calculate as follows: Any Number1Any~Number-1

Consecutive numbers sequence

Consecutive numbers from smallest to largest are numbers that follow one another in ascending order,
For example:
23,24,25,2623,24,25,26

Sum of Consecutive Numbers

The sum of consecutive numbers is the addition of all consecutive numbers we have.
For example -
23+24+25+2623+24+25+26
We can use the commutative and associative properties and calculate as seen below:
23+25=4523+25=45
24+26=5024+26=50
50+45=9550+45=95
