Question

The sum of three consecutive integers is -27. What are the numbers?

Answer 1

They are `-10, -9, -8`.

Explanation:

A number can be `n`. Then its consecutive is `n+1` and the following consecutive is `n+2`.

We are asking then

`n+(n+1)+(n+2)=-27`

or

`3n+3=-27`
`3n=-30`
`n=-10` and, consequently, the other two are `n+1=-9` and `n+2=-8`.

The three numbers are `-10, -9, -8` and the sum is `-27`.
