Step 3) Show that ( k +1)! ≥ 2 k+1. ( k +1)! = k ! ( k +1) Rewrite ( k +1)! in terms of k ! ≥ 2 k ( k +1) Use step 2 and the multiplication property. ≥ 2 k (2) k +1 ≥ 5 >2, so we ...
WebIf we only use S(k-1) we must verify the first two base cases. If we use S(k-2) we must verify the first three base cases etc. But by definition we must verify at least two base cases otherwise we are using weak induction. Thus, in strong induction we verify as many cases as needed according to how great a gap is the inductive step. WebThe inductive step for structural induction is usually proved by some simple property that follows from a recursive definition for the structure. Structural induction is also used to prove properties with many base cases (as in generalized induction on well-founded sets) and can even be applied with transfinite induction (see Chapter 4).
