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.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

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.
