I forwarded that to a math professor I know.

OK, a mathematical solution:
Evenvalued terms are every 3 terms (as the Fibonacci sequence mod 2 is 0, 1, 1, 0, 1, 1, 0, ...). There is a formula for the nth term of the Fibonacci sequence which goes as follows: There are 33 fibonacci numbers (starting with F(1) = 1) less than 4 million. Therefore the sum is: In order to prevent extra math, we figure out the denominators now. Therefore by crossmultiplying we get ETA: My nerditude has reached a maximum. =Uncool Last edited by uncool; 04192012 at 12:21 AM.

There's a ton of equations relating to Fibonacci numbers.
Another way to calculate the solution: For the sum of every third member of the series starting from n = 0: From this recurrence and the first 3 terms of the sum we get the matrix equation:
