Re: Fibonacci series

Hi;

Welcome to the forum. There simplest is called the Binet formula.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Hi;

http://en.wikipedia.org/wiki/Fibonacci_number

About 1 / 3 down the page there is an explanation for how to do the sum by grouping.
