**Python program to calculate n-th term of Fibonacci series** with the help to two approaches (there are many approaches to calculate n-th term).

**Description:**

**First Approach: Dynamic Programming**

In this approach, we calculate all the terms of Fibonacci series up to n and if we need to calculate any other term which is smaller than n, then we don’t have to calculate it again.
**Second Approach: By Formula**

In this approach we calculate the n-th term of Fibonacci series with the help of a formula.

**Formula:**
phi = ( 1 + sqrt(5) ) / 2
An = phin/ sqrt(5)

**Example:**

Input:
for n = 5
for n = 8
Output:
a5 = 5
a8 = 21
