Why is the fibbonacci sequence special?

Answer 1

There is no fibbonacci sequence. The Fibonacci sequence was devised as a relatively simple growth sequence. It has the property that the ratio of the numbers of the sequence divided by the preceding number in the sequence tends towards phi, the Golden Ratio = [1 + √5]/2 which has important geometric properties.

Also, there are very many instances in nature where the Fibonacci sequence may be found.
