WebWe need to show that the statement is also true for k + 1, i.e., (k + 1)^3 - (k + 1) is divisible by 6. We can expand (k + 1)^3 as follows: (k + 1)^3 = k^3 + 3k^2 + 3k + 1 Subtracting k from both sides, we get: (k + 1)^3 - (k + 1) = k^3 + 3k^2 + 2k. Step-by-step explanation. Now, using the fact that k^3 - k is divisible by 6 (by our induction ... dog face jackeWeb= k^3 + 3k^2 + 8k + 6 So f (k + 1) - f (k) = 3k^2 + 3k + 6 = 3 (k^2 + k + 2) = 3 [k (k + 1) + 2] k or k + 1 must be even so k (k + 1) is even and k (k + 1) + 2 is also even So f (k + 1) - f (k) is divisible by 6.
