  1. Fibonacci Number

    In mathematics, the Fibonacci numbers, commonly denoted F? form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is, F?=0, F?=1, and F?=F???+F???, for n > 1. One has F? = 1. In some books, and particularly in old ones, F?, the "0" is omitted, and the Fibonacci sequence starts with F? = F? = 1. The beginning of the sequence is thus: (0,) 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, … Fibonacci numbers are strongly related to the golden ratio: Binet's formula expresses the nth Fibonacci number in terms of n and the golden ratio, and implies that the ratio of two consecutive Fibonacci numbers tends to the golden ratio as n increases.
