Fibonacci Sequence Using Recursion in R

In this article, you find learn to print the fibonacci sequence by creating a recursive function, recurse_fibonacci().

To understand this example, you should have the knowledge of the following R programming topics:

The first two terms of the Fibonacci sequence is 0 followed by 1. All other terms are obtained by adding the preceding two terms.

This means to say the nth term is the sum of (n-1)th and (n-2)th term.

The Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21

Example: Fibonacci Sequence in R

# Program to display the Fibonacci sequence up to n-th term using recursive functions



How many terms? 9
[1] "Fibonacci sequence:"
[1] 0
[1] 1
[1] 1
[1] 2
[1] 3
[1] 5
[1] 8
[1] 13
[1] 21

Here, we ask the user for the number of terms in the sequence.

A recursive function recurse_fibonacci() is used to calculate the nth term of the sequence. We use a for loop to iterate and calculate each term recursively.

See this page to find out how you can print fibonacci series in R without using recursion.
