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 agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Fibonacci series

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.
