tn - tn-1 = 2n + 3; t1 = 10
Find the first five terms in the sequence using this recursive formuls

  • Math -

    or
    t(n) = t(n-1) + 2n + 3

    t(1) = 10
    t(2) = t(1) + 4+3 = 10+7 = 17
    t(3) = t(2) + 6+3 = 17+9 = 26
    t(4) = t(3) + 8+3 = 26+11 = 37
    t(5) = t(4) + 10+3 = 37+13 = 40
