I think
1+3+5+7+9+11+13+15+17+19+21+23+25+27=196
answer:196/14=14
but I am not sure

you are correct. Why would you not be sure, unless you don't trust tour addition?
Just FYI, the sum of the 1st n odd numbers is n^2, so in this case the sum is indeed 14^2.
So, the average of the 1st n odd numbers is always n^2/n = n.
