I can give you about 10-15 numbers in the sequence.
1,1,2,3,5,8,13,21,34,55,89
There's 11. Anyone else want to continue on afterwards?
The nth Fibonacci number is given by :
F(n) = [ Phi^n - [-phi]^n ] / √ 5
Where Phi = [ 1 + √5] / 2
And phi = 2 / [ 1 + √5 ]
Well, this is all about adding the number that is before that number with your answer.
FOR EXAMPLE:
1+1=2
2+1=3
3+2=5
5+3=8
and so on.
