WebThe principle of mathematical induction (often referred to as induction, sometimes referred to as PMI in books) is a fundamental proof technique. It is especially useful when proving that a statement is true for all positive integers n. n. Induction is often compared to toppling over a row of dominoes. WebMar 19, 2024 · Bob was beginning to understand proofs by induction, so he tried to prove that f ( n) = 2 n + 1 for all n ≥ 1 by induction. For the base step, he noted that f ( 1) = 3 = 2 ⋅ 1 + 1, so all is ok to this point. For the inductive step, he assumed that f ( k) = 2 k + 1 for some k ≥ 1 and then tried to prove that f ( k + 1) = 2 ( k + 1) + 1.
