Question

If 15 is the fifth number in a series of five consecutive odd numbers what is the third number in the series ?

What is the answer is 11 or 9 ?? I think it's 11.  What is yr answer ??

Answer 1

`15 - 5th\\ 13 - 4th\\ \boxed{11} - 3rd`

Answer 2

It doesn't matter how many there are altogether.

All you need to know is that 15 is the fifth odd number,
and you need the third odd number.

So the one you want is 2 odd numbers back from 15. That's 11 .
