Fabonacci Sequence Numbers

I have found another way of finding the terms of a fibonacci numbers.   
                2          2
Fn sad  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

Re: Fabonacci Sequence Numbers

Your notation is not showing up probably.
There are ways to show the fibonacci numbers (eg. phi).

Re: Fabonacci Sequence Numbers

Hi sthiruvikraman26;

I can not make out anything of what you have written. You could latex it up

Your last one:

Is true.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
