The nth term is given by......
[ Phin - (-phin )] / √5 where Phi = [1 + √5]/ 2 .... and phi is the reciprocal of this
BTW....this is known as "Binet's" Formula
Surprisingly enough....the irrational number in the denominator might lead you to believe that this "formula" would produce an irrational result....but it doesn't.....!!!!
