Mubashir is trying to figure out the corresponding quadratic formula for the following quadratic sequence of numbers:
| N | Result |
|---|---|
| 1 | 90 |
| 2 | 240 |
| 3 | 450 |
| 4 | 720 |
| 5 | 1050 |
If you can figure this out, then help him by creating a function that takes a number n and returns the nth number of this quadratic sequence.
