Question

You can represent an odd integer with the expression 2n+1, where n is any integer. write and solve an equation to find three consecutive odd integers that have a sum of 63.

Answer 1

I :  2n + 1 
II : 2n + 3
III : 2n +5
(2n + 1) + (2n + 3) +(2n+5)=63
6n+9=63
n=9
I : 2n+1=9*2+1=19
II : 2n+3=9*2+3=21
III : 2n+5=9*2+5=23

19+21+23=63
