WebbThus, 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 ... WebbFibonacciNumbers The Fibonacci numbersare defined by the following recursive formula: f0 = 1, f1 = 1, f n = f n−1 +f n−2 for n ≥ 2. Thus, each number in the sequence (after the first two) is the sum of the previous two numbers. dr joy chen
