WebMar 15, 2016 · O (2^ (n+1)) is the same as O (2 * 2^n), and you can always pull out constant factors, so it is the same as O (2^n). However, constant factors are the only thing you can pull out. 2^ (2n) can be expressed as (2^n) (2^n), and 2^n isn't a constant. So, the answer to your questions are yes and no. Share. Improve this answer. WebBasic Math. Solve for a an=2n-1. an = 2n − 1 a n = 2 n - 1. Divide each term in an = 2n− 1 a n = 2 n - 1 by n n. an n = 2n n + −1 n a n n = 2 n n + - 1 n.

WebHint only: For n ≥ 3 you have n 2 > 2 n + 1 (this should not be hard to see) so if n 2 < 2 n then consider. 2 n + 1 = 2 ⋅ 2 n > 2 n 2 > n 2 + 2 n + 1 = ( n + 1) 2. Now this means that the induction step "works" when ever n ≥ 3. However to start the induction you need something greater than three. WebIn general, be wary of the proofs by implications of that sort -- it is easy to miss a step, or to think an implication is an equivalence. Most of the time, what you want can be written as a succession of (in)equalities, but less tricky to handle. WebBasic Math. Solve for a an=2n-1. an = 2n − 1 a n = 2 n - 1.
