[QUOTE="uart, post: 6523548, member: 3399"] Thanks all. Yes I did try induction first up, but I didn't get anywhere with it. That's a great approach anuttarasammyak, looks very promising. And using the combinations property that, [tex] _nC_r = \, _{n-1}C_r + \, _{n-1}C_{r-1}[/tex] with the end condition that [itex] _nC_0 = \, _{n-1}C_0[/itex], I'm pretty sure I can make that whole LHS "telescope".
