Three good friends are in the same algebra class. Their scores on a recent test are three consecutive odd integers whose sum is 255. Find scores

Question

I don’t know how to do this problem

Answer 1

Let the scores be 2n-1, 2n+1 and 2n+3.

The sum of the scores is 6n+3 = 255

6n = 252 => n = 42

The scores are 83, 85 and 87.
