I have found another way of finding the terms of a fibonacci numbers.

2 2

Fn F ) - ( F ) ;where x+y=n and y=x-2.

n-x n-y

(or) Fn th term of the sequence is equal to the difference of squares of two fibonacci numbers F and F

n-x n-y

where x+y=n and y=x-2

sum of first n terms of a fibonacci sequence is,

Sn = ( F ) - 1

n+2

Your notation is not showing up probably.

There are ways to show the fibonacci numbers (eg. phi).
