Question

The sum of three consecutive integers can be represented by?

Answer 1

If `n` is the first of the three numbers, the formula is `3n+3`

Explanation:

Let's say that you start from the integer `n`. The three consecutive numbers are thus `n`, `n+1` and `n+2`.

Let's compute the sum:

`n+(n+1)+(n+2)=n+n+n+1+2=3n+3`
