Algorithm and Flowchart to find Fibonacci series1 min read

In this tutorial, we will write an algorithm to find the Fibonacci series, we will also learn to draw the flowchart to find the Fibonacci series for a number. You may go through the following topic first.

Let us first understand what is fibonacci series.

Fibonacci series is the series of numbers where the next number is achieved by the addition of the previous two numbers. The initial addition of two numbers is 0 and 1. For example: 0,1,1,2,3,5,8,13….etc.

Let us start with a flowchart of a fibonacci series.

Flowchart to calculate the fibonacci series

The above flowchart diagram is to find the Fibonacci series.


Algorithm of Fibonacci Series

Step 1: START
Step 2: Declare variable n1, n2, sum, n, i
Step 2: Initialize variables:
n1 = 0, n2 = 1, i = 2
Step 3:  Read n
Step 4: Repeat this step until i <= n:
sum = n1 + n2
print sum
n1 = n2
n2 = sum
i = i + 1
Step 5: STOP

This is the algorithm and flowchart of fibonacci series. If you want to understand through code, you may follow the below link:
