A pentagonal number is defined $\frac{3n^2-n}{2}$

For $n=1,2,$dots, and son on$.$

Therefore, the first few numbers are $1,5,12,22,$dots.

Create a method with the following header that returns a pentagonal number:

public static int getPentagonalNumber$($int $n)$

For example, getPentagonalNumber $(1)$ returns $1$ and getPentagonalNumber $(2)$ returns $5.$

Create a test program$($class$)$ that uses this method to display the first $100$ pentagonal numbers with $10$

numbers on each line. Use the $7d$ format to display each number.
