The sequence of triangle numbers is generated by adding the natural numbers. So the 7th triangle number would be: 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten triangle numbers are: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55 The factors of the first seven triangle numbers are:

1: 1 3: 1,3 6: 1,2,3,6 10: 1,2,5,10 15: 1,3,5,15 21: 1,3,7,21 28: 1,2,4,7,14,28

We can see that 28 is the first triangle number to have over five divisors. Using C#, Create a method called FindTriangleNumber() that returns the first triangle number to have over 250 divisors.
