Question

What are three consecutive integers whose sum is 87?

Answer 1

28, 29, 30

Explanation:

We can think of the consecutive integers as the numbers `x-1, x, x+1`. Because we're told the sum is 87, we can write an equation:
`(x-1)+(x)+(x-1)=87`
`3x=87`
`x=29`
So know we know that `x`, the middle number, is 29, so the two numbers next to it are 28 and 30. So the correct list of integers is 28,29,30
