Given the **A **and **R **i,e first term and common ratio of a GP series. Find the Nth term of the series.

**Example 1:**

**Input: **A = 2, R = 2, N = 4
**Output: **16
**Explanation: **The GP series is
2, 4, 8, 16, 32,... in which 16
is th 4th term.

**Example 2:**

**Input: **A = 4, R = 3, N = 3
**Output: **36
**Explanation: **The GP series is
4, 12, 36, 72,.. in which 36 is
the 3rd term.

**Your Task:**

You don't need to read or print anything. Your task is to complete the function **Nth_term()** which takes A, R and N as input parameter ans returns Nth term of the GP series modulo 10^{9} + 7.

**Expected Time Complexity:** O(log_{2}(N))

**Expected Space Complexity: **O(1)

**Constraints:**

1 <= A, R, N <= 1000000
