Given a number n, find the n-th centered cube number.
The Centered cube number counts the number of points which are formed by a point that is surrounded by concentric cubical layers in 3D with i2 points on the square faces of the i-th layer. Source[WIKI]. Please see this image for more clarity.
The first few Centered cube numbers are:
1, 9, 35, 91, 189, 341, 559, 855, 1241, 172…………………………
Input : n = 1 Output : 9 Input : n = 7 Output : 855
Mathematical formula for nth centered cube number is given by:
n-th Centered Cube Number = (2n + 1)(n2 + n + 1)
Below is the basic implementation of the above formula:
3th Centered cube number: 91 10th Centered cube number: 2331
- Centered Octahedral number
