A Fibonacci sequence is the integer sequence of 0, 1, 1, 2, 3, 5, 8....

The first two terms are 0 and 1. All other terms are obtained by adding the preceding two terms. This means to say the any term n in the sequence is the sum of (n-1)th and (n-2)th term. For example:

The 4th term is 3rd + 2nd numbers in the series --> 1 + 1

The 5th term is 4th + 3rd numbers in the series --> 2 + 1

Do this using a recursive function for the first 20 terms.
