Given a number N, the task is to find Nth Hexacontagon number.
A Hexacontagon number is class of figurate number. It has 60 – sided polygon called hexacontagon. The N-th hexacontagon number count’s the 60 number of dots and all others dots are surrounding with a common sharing corner and make a pattern. The first few hexacontagonol numbers are 1, 60, 177, 352 …
Input: N = 2
The second hexacontagonol number is 60.
Input: N = 3
Approach: The N-th hexacontagon number is given by the formula:
- Nth term of s sided polygon =
- Therefore Nth term of 60 sided polygon is
Below is the implementation of the above approach:
3rd hexacontagon Number is = 177
