Given the first 2 terms A1 and A2 of an Arithmetic Series.Find the N^th term of the series. 

Example 1:

Input:
A1=2
A2=3
N=4
Output:
5
Explanation:
The series is 2,3,4,5,6....
Thus,4th term is 5.

 

ANSWER:

 

int nthTermOfAP(int A1, int A2, int N) {
      int result;
      int diff=A2-A1;
      result=A1+(N-1)*diff;
      return result;
    }
