    Prove telescoping series:
    Let a_n from n=0 to infinity be a sequence of real numbers which converge to 0, i.e. lim n-->infinity a_n=0. Then the series of the sum from n=0 to infinity of (a_n - a_n+1) converges to a_0.

    Hint: first work out what the partial sums of the sum from n=0 to N of (a_n - a_n+1) should be, and prove your assertion using induction.
