Given a number N, the task is to find Nth Icosihexagon number.
An Icosihexagon number is class of figurate number. It has 26 – sided polygon called Icosihexagon. The N-th Icosihexagonal number count’s the 26 number of dots and all other dots are surrounding with a common sharing corner and make a pattern. The first few Icosihexagonol numbers are 1, 26, 75, 148 …
Input: N = 2
The second Icosihexagonol number is 26.
Input: N = 3
Approach: The N-th Icosihexagonal number is given by the formula:
- Nth term of s sided polygon =
- Therefore Nth term of 26 sided polygon is
Below is the implementation of the above approach:
3rd Icosihexagonal Number is = 75
