Let me start off by saying, I am terrible at math. I'm not even sure if I know how to explain this for you to understand, but here goes.

I am trying to obtain an equation for series of numbers, with a repeating pattern.

- The numbers must be greater or equal to
*n*.
- The first series of numbers, must compose of
*n* whole numbers after *n*.
- After the first, and each series of numbers,
*n* numbers must be excluded, followed by *n* series of numbers, and so on..

ex.

*n* = 4

would result in...

4, 5, 6, 7, 12, 13, 14, 15, 20, 21, 22, 23....

*n* = 2

2, 3, 6, 7, 10, 11...

Thanks a lot in advance.
