The Fibonacci numbers are the numbers in the following integer sequence
0,1,1,2,3,5,8,.13,21,34,55
By definition, the first two Fibonacci numbers are 0 and 1, and each subsequent number is the sum of the previous two. Some sources begin the sequence with two 1s.
The Fibonacci sequence is named after Leonardo of Pisa, known as Fibonacci (a contraction of filius Bonacci, "son of Bonaccio"). Fibonacci sequences are used in finance and also appear in biological settings, such as branching in trees and in the model for the pattern of florets in the head of a sunflower. There is a formula which explains how the seeds pack together with the greatest efficiency, resulting in a spiral pattern.
