1. The problem statement, all variables and given/known data Prove if n[tex]\geq[/tex]4, n!>2n. 2. Relevant equations 3. The attempt at a solution Proof: (by induction) Prove for n=4 4!>24 24>16 true for n=4 Prove for n+1 n! (n+1) > 2n (n+1) (n+1)! > 2n (n+1) This is where I get stuck. I don't know where to go from here.
