WebThe natural induction argument goes as follows: F ( n + 1) = F ( n) + F ( n − 1) ≤ a b n + a b n − 1 = a b n − 1 ( b + 1) This argument will work iff b + 1 ≤ b 2 (and this happens exactly when b ≥ ϕ ). So, in your case, you can take a = 1 and you only have to check that b + 1 ≤ b 2 for b = 2, which is immediate. WebProof (using the method of minimal counterexamples): We prove that the formula is correct by contradiction. Assume that the formula is false. Then there is some smallest value of nfor which it is false. Calling this valuekwe are assuming that the formula fails fork but holds for all smaller values.
