    Braindrain

    Hi!

    I was wondering if someone could help me answer this problem:


    1. Let Fn denote the nth term in the Fibonacci sequence 0, 1, 1, 2, 3, 5, 8, 13, ... (we start with
      the 0th term 0). Show that the sum of Fsubn over 7^n = 7/41.

      Note: the sequence is infinite

      Thanks!
