WebbMathematical induction can be used to prove that an identity is valid for all integers n ≥ 1. Here is a typical example of such an identity: 1 + 2 + 3 + ⋯ + n = n(n + 1) 2. More … Webb16 aug. 2024 · An Analogy: A proof by mathematical induction is similar to knocking over a row of closely spaced dominos that are standing on end.To knock over the dominos in Figure \(\PageIndex{1}\), all you need to do is push the first domino over. To be assured that they all will be knocked over, some work must be done ahead of time.
