WebbQ) Use mathematical induction to prove that 2 n+1 is divides (2n)! = 1*2*3*.........* (2n) for all integers n >= 2. my slution is: basis step: let n = 2 then 2 2+1 divides (2*2)! = 24/8 = 3 True inductive step: let K intger where k >= 2 we assume that p (k) is true. (2K)! = 2 k+1 m , where m is integer in z. Webb15 nov. 2011 · 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 ).
