  6. follow R_scott's suggestion

    when n = 1 , 2n+3 = 2(1) + 3 = 5
    when n = 2 , 2n+3 = 2(2) + 3 = 7
    when n = 3, 2n+3 = 2(3) + 3 = 9
    ....

    What do you notice about the output numbers?
    How does that tie in with 2n+3 ?

    The excuse " I am clueless in math" is such a lame one.
    With a little bit of effort and trying to understand what you are doing
    will bring you away from being "clueless"
