 SeveredCross 2^1, 2^2, 3*5 Jafet Duh, 24 of course. aegray 42 SeveredCross I don't see it. Jafet s/24/42 action aegray wins! aegray wins! SeveredCross 3*n-n?Nope.Not right Jafet f(n) => 2 if n = 1, 4 if n = 2, 15 if n = 3, 0 otherwise. SeveredCross Bah Okfdewqd can't figure out what kind of pattern it is SeveredCross Me either.Not geometric, not algebraic.Maybe it's 3 times the previous term - the previous term?Nope, not right.15 fails.Hmm. _kmh_ hi SeveredCross Isn't there a way to derive that using linear algebra? multi_io (2+1)*(4+1)=15, (4+1)*(15+1)=80such "exercises" are retarded anyway :P whaleofconfusion it's probably 23 SeveredCross Why 23? whaleofconfusion nah nm SeveredCross multi_io has a good idea IMO. _kmh_ what's the problem ? whaleofconfusion a ridiculous problem, a sequence with only 3 elts SeveredCross Find the next element whaleofconfusion and you're supposed to guess from that what comes next SeveredCross ie. find the generating function. _kmh_ hmmm one of those ?:)generating function ? whaleofconfusion Okfdewqd: where did you see this problem? SeveredCross I know that's not the proper usageBut I just call it that _kmh_ ah ok SeveredCross I knew it was only a matter of time before someone called me on it.But I just look at those sequences as the outputs to a function _kmh_ sobasicaly you want to continue the sequence ?
