WebTherefore we write k 2 + k = 2A. Step 1. Show that the base case is divisible by 2. Step 2. Assume that the case of n = k is divisible by 2. Step 3. Use this assumption to prove that the case where n=k+1 is divisible by the given value. This is the inductive step in which most of the algebra is conducted. WebApr 20, 2024 · Induction Step: Prove if the statement is true or assumed to be true for any one natural number ‘k’, then it must be true for the next natural number. 3^ (2 (k+1)) — 1 = 8B , where B is some constant. = 8B , where B= (3^ (2k) + C), we know 3^ (2k) + C is some constant because C is a constant and k is a natural number.
