Web15 nov. 2011 · 159. 0. For induction, you have to prove the base case. Then you assume your induction hypothesis, which in this case is 2 n >= n 2. After that you want to prove that it is true for n + 1, i.e. that 2 n+1 >= (n+1) 2. You will use the induction hypothesis in the proof (the assumption that 2 n >= n 2 ). Last edited: Apr 30, 2008.
