How to solve a recursive sequence
WebThe key to solving this puzzle was using a binary search. As you can see from the sequence generators, they rely on a roughly n/2 recursion, so calculating R(N) takes about 2*log2(N) recursive calls; and of course you need to do it for both the odd and the even. Webthe previous terms in the sequence. In particular, we need only save two pieces of information - the two previous terms - at every step. We can then compute the next pair of points as follows: (a n;a n 1) = (2a n 1 + 3a n 2;a n 1) That is, we nd the next term in the sequence, and we have to keep a n 1 around for the next iteration.
