Question

The sum of 3 consecutive odd integers is -129, how do you find the integers?

Answer 1

I got: `-45,-43 and -41`

Explanation:

Consider our three odd integers as:
`2n+1`
`2n+3`
`2n+5`

So that:

`2n+1+2n+3+2n+5=-129`

`6n+9=-129`

`n=-138/6=-23`

so that the numbers will be:

`2n+1=-45`
`2n+3=-43`
`2n+5=-41`
