a)
1 = 1
2 = 3
3 = 6
4 = 10
5 = 15
6 = 21
7 = 28
8 = 36
9 = 45
10 = 55

b) Honestly, the only pattern I see is just the next number is adding by 1, 2, 3, etc.

c) I think that there is a formula to this question, but I can't seem to figure it out.
I do think the formula would be something like the Fibonacci sequence formula, that if you have two consecutive numbers (ex. 15 and 21) you would be able to find the next number by adding 7, because you can figure that 21 - 15 = 6 so the next number would be 21 + 7.

d) I think that if there is a formula, it would have to have been proved if people use it.
