the five numbers can be represented by (2n+1), (2n+3), (2n+5), (2n+7) and (2n+9) where
n is an integer.
2n+9 = 15
n = 3

The third number is 2n+5 = 11

You really don't have to do hardly ANY work to solve this one.

The fifth of five odd numbers is 15.

So the fourth one is 13.

So the third one is 11.

An I missing something ?
