Fibonacci's Story

by: Kelli Nipper


Fibonacci's sequence of numbers (1, 1, 2, 3, 5, 8, 13, 21...) was introduced by the following problem:

Suppose rabbits breed in such a way that each pair of adult rabbits produces a pair of baby rabbits each month. The first month after birth, the rabbits are adolescents and produce no off-spring. However, beginning with the second month, the rabbits are adults and each pair produces a pair of offspring every month.
