Concept : Fibonacci number

Given : The Fibonacci numbers were first introduced in Fibonacci's book,

            "Liber abaci" in a question to find the population of an animal at a

             particular time.

To find : What animal did he use

Explanation:

Fibonacci number is a series in which the next number is the sum of the previous two numbers of the series.

The first two numbers of the Fibonacci series are fixed, they are 0 and 1.

Example :

First term : 0

Second term : 1

Third Term : 0 + 1 = 1 (first + second term)

Fourth Term : 1 + 1 = 2 (second + third term)

Fifth Term : 1 + 2 = 3 (third + fourth term)

Sixth Term : 2 + 3 = 5 (fourth + fifth term)

And so on.....

The animal which he used was rabbit.
