Fibonacci sequence

  1. Aug 30, 2008 #1
    if [tex]a_1, a_2, a_3 .............[/tex] belong to the fibonacci sequence, prove that

    [tex]a_1a_2 + a_2a_3 + ............ + a_{2n-1}a_{2n} = (a_{2n})^2[/tex]

    If you are familiar with mathematical induction then that's the way to go with this one. Using the recursion equation ([itex]a_{2n} + a_{2n+1} = a_{2n+2}[/itex] etc) should let you make the inductive step fairly easily.

    BTW. Is this homework ?

    Is there any other method other than this?
