### 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.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

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.
