Paul January 29, 2012 at 7:00 pm Can someone explain this one? If I have three partners, and they each have three partners, that’s 13 people. Where did the 7 come from?
Otto Bob Otto January 30, 2012 at 5:02 pm I’d explain it.. but then I’d be wrong. I don’t know how this works.
David January 30, 2012 at 6:33 pm From what I can see, this a recursion with closed form a_n=2^n-1. Why?
Otto Bob Otto February 2, 2012 at 2:11 pm No I got that a_n = 2^n – 1… I just don’t get how it models this situation. At all. Ever.
