WebYour inductive step needs to build off of your base case (s). If your base case was just P (12) then you would have to show that you can make 13 cents in stamps from 12 cents in stamps and 4 and 5 cent stamps. If you can make n cents, if you add a 5 cent stamp and remove a 4 cent stamp to make n + 1. WebProve the inductive step: This is where you assume that all of P (k_0) P (k0), P (k_0+1), P (k_0+2), \ldots, P (k) P (k0 +1),P (k0 +2),…,P (k) are true (our inductive hypothesis). Then …
