Peter Bengtsson pose la question :
Can you help me find an equation for this correlation?

2*1+1
3*2+0
4*2+2
5*3+0
6*3+3
7*4+0
8*4+4
9*5+0
10*5+5

This is the way scores are calculated when you play the game Cascade. The more number of balls you manage to "click away", the better score you get. So, I wrote down lots of results for different amount of balls I clicked away. Clicking away one pair (two adjacent) of balls means 3 points. Clicking away three adjacent balls means 6 points. etc. You can see this from the list above.

What I now want to do is to find an equation with only ONE unknown! Y= kn*X+c or something. Whereby I only know X, I can find Y.
