What is Fibonacci Series
The Fibonacci series is a sequence of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1. The sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on. It is named after the Italian mathematician Leonardo Fibonacci, who introduced the series to Western mathematics in his book Liber Abaci, which was published in 1202. The Fibonacci series has many interesting properties and appears in many areas of mathematics, as well as in art, music, and nature.
