WebJun 27, 2024 · The Fibonacci series is a series of numbers in which each term is the sum of the two preceding terms. It's first two terms are 0 and 1. For example, the first 11 terms of the series are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and 55. In mathematical terms, the sequence Sn of the Fibonacci numbers is defined by the recurrence relation: WebWhen a function calls itself, then its called recursion. That is the most basic definition. This definition is enough when you need to solve basic problems like fibonacci series, factorial, etc. This is the implicit use of recursion.
