Question

What are three consecutive numbers that add up to 48?

Answer 1

`15`, `16`, `17`

Explanation:

If the second number is `n`, then the first and third are `n-1` and `n+1` and we have:

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

Divide both ends by `3` to find `n=16`

So the threee numbers are `15`, `16` and `17`.
