## How do you find the sum of consecutive numbers?

By using Carl Gauss’s clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly.

We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal..

## What is the sum of three consecutive numbers is 72?

23 24 25. Therefore, the three consecutive numbers whose sum is 72 are 23, 24, and 25, and 23 is certainly the smallest. x+1 and x+2. The smallest of the three integers is modeled by the variable x, so this is our answer.

## What three consecutive numbers have a sum of 123?

Therefore, three consecutive integers that add up to 123 are 40, 41, and 42.

## What are the three consecutive numbers?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.
