WebBy the induction hypothesis, the second player can now win this game because there are two piles with n k stones in each, 0 n k < n, and it is the rst player’s turn. Thus, the second player has a strategy by which to win a game of Nim with n stones, and P(n) holds, completing the induction. Webinduction 1 Consider a game with 2 players that take turns removing any positive number of matches they want from one of two piles of matches. The player that removes the last match wins the game. Prove that if both piles contains the same number of matches initially, the second player can always guarantee a win.

WebUsing 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.
