Find the average of the first 14 positive odd integers.

  • math help -

    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.
