Question

If the sum of three consecutive integers is `81` then what are the three integers?

Answer 1

`26, 27, 28`

Explanation:

Denote the middle integer by `n`. Then the three consecutive integers are:

`n-1, n, n+1`

Then we have:

`81 = (n-1)+n+(n+1) = 3n`

Dividing both ends by `3` we find:

`n = 27`

So the three integers are:

`26, 27, 28`
