Hey!
So, I kinda need some help...
I'm trying to work out the nth term of this, but it's beginning to get hard, I remember when it goes into the nth term term you need to square things, and stuff...
Code:
2)  100,000
           - 200,000
3)  300,000         - 100,000 
           - 300,000
4)  600,000         - 100,000
           - 400,000
5)1,000,000


			2) 50,000
			3)100,000
			4)150,000
			5)200,000
			50(n-1)

2) 50,000
3)200,000
4)450,000
5)800,000
-
That was just my rough working out, if you can understand any of it, a head-start. Otherwise, my pattern is
Code:
2)  100,000
3)  300,000
4)  600,000
5)1,000,000
I've forgotten how to do this, and all of the online sites are useless!
Thanks if anyone helps.
