That’s why I spend my Friday nights… uh…
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?
I’d explain it.. but then I’d be wrong. I don’t know how this works.
From what I can see, this a recursion with closed form a_n=2^n-1. Why?
No I got that a_n = 2^n – 1… I just don’t get how it models this situation. At all. Ever.
