WebbUsing induction, prove that for any positive integer k that k 2 + 3k - 2 is always an even number. k 2 + 3k - 2 = 2 at k=1 k 2 - 2k + 1 + 3k - 3 - 2 = k 2 + k = k (k+1) at k= (k-1) Then we just had to explain that for any even k, the answer would be even (even*anything = even), and for any odd k, k+1 would be even, making the answer even as well.

WebbThe above proof was not obvious to, or easy for, me. It took me a bit, fiddling with numbers, inequalities, exponents, etc, to stumble upon something that worked. This will often be the hardest part of an inductive proof: figuring out the "magic" that makes the induction step go where you want it to. There is no formula; there is no trick.

WebbStrong Induction appears to make it easier to prove things. With simple induction, one must prove P(n+1) given the inductive hypothesis P(n); with strong induction one gets to assume the inductive hypothesis P(0)^P(1)^:::^P(n), which is much stronger. Consider the following example, which is one half of the Fundamental Theorem of Arithmetic ...

These ideas are illustrated in the next example. Example 4 Consider the sequence defined by b(0) = 0 b(1) = 1 b(n) = b(jn 2 k) +b(ln 2 m), for n ≥ 2. If you look at the first five or six terms of this sequence, it is not hard to come up with a very simple guess: b(n) = n.
