For any other value of N, Fibonacci(N) returns the sum of Fibonacci(N-1) and Fibonacci(N-2).
In the recursive solution, we will define a function Fibonacci() that takes a number N as input and returns the term at the Nth position in the Fibonacci series.įor N=1, the function returns 0 while it returns 1 for N=2. As we define a term in the Fibonacci series using its previous terms, we can easily create a recursive solution for determining the term at any position in the Fibonacci series using recursion in Python. You might be knowing that we can solve a problem using recursion if we can break the problem into smaller sub-problems. Determine Fibonacci Series Using Recursion In Python Instead of using a while loop, we can also use a for loop to determine the Fibonacci series in Python as follows. Output: 10 terms of the fibonacci series are: Print("10 terms of the fibonacci series are:") # finding 10 terms of the series starting from 3rd term To store the terms, we will use a python list. We can start with the first and second terms and find other terms in the Fibonacci series using a for loop or while loop in python.įor instance, to find the number at the Nth position in the Fibonacci series, we will execute a while loop N-2 times to calculate the terms from the 3rd position to the Nth position. To determine the Fibonacci series in python, we can simply use the methodology used above.

How To Determine Fibonacci Series In Python? We can find the number at any position in the Fibonacci series using the above formula. Using the above formulae, we can find the number at any position in the Fibonacci Series. Mathematically, A Fibonacci series F can be defined as follows.
