Python code to find Nth term in Fibonacci series

 

Find the Nth term in the Fibonacci series.

Note: Here Fibonacci series starts with 1 not with 0 {1,1,2,3,5}.

Input Format :

Nth term.

Output Format :

 Return its equivalent Fibonacci number.

Explanation of Input :

The number is ‘5’ so we have to find the “5th” Fibonacci number
So by using the property of the Fibonacci series i.e 

[ 1, 1, 2, 3, 5, 8]
So the “5th” element is “5” hence we get the output.

Sample Input :

6

Sample Output :

8

Solution :

1. N = int(input())
2. temp = 1
3. a = 1
4. b = 0
5. c = 0
6. if N == 1:
7.     c = 1
8. else:
9.     while temp < N:
10.         c = a + b
11.         b = a
12.         a = c
13.         temp = temp + 1
14. print(c)
