What is the sum of following product of Fibonacci numbers

$$\sum_{k=1}^{n-1} Fib(k)*Fib(n+3-k)$$

can anyone suggest only approach to find general term?

    In the usual numbering, $fib(0) = 0, fib(1) = 1, fib(2) = 1, fib(3) = 2, fib(4) = 3$2012-09-03

    My first thought is Binet's + geometric sum formula.2012-09-03

    Rahul, if you don't get the answer you want on a question, you edit the question. You don't post a rehash of the old question.2012-09-03
