WebThus, by induction, N horses are the same colour for any positive integer N, and so all horses are the same colour. The fallacy in this proof arises in line 3. For N = 1, the two groups of horses have N − 1 = 0 horses in common, and thus are not necessarily the same colour as each other, so the group of N + 1 = 2 horses is not necessarily all ... WebSo, even though (*) was true for n = 1, it was not true for n = 2, and (*) fails, as we knew it ought to. As the above example shows, induction proofs can fail at the induction step. If we can't show that ( * ) will always work at the next place (whatever that place or number is), then ( * ) simply isn't true. hawaiian mai tai recipe easy
