WebJan 12, 2024 · Many students notice the step that makes an assumption, in which P(k) is held as true. That step is absolutely fine if we can later prove it is true, which we do by proving the adjacent case of P(k + 1). All the steps … WebStrong induction is a useful variant of induction. Here, the inductive step is changed to Base case: The statement is true when n = 1. Inductive step: If the statement is true for all values of 1 n < k, then the statement is also true for n = k. This also produces an in nite chain of implications: The statement is true for n = 1
