In precalculus, discrete mathematics or real analysis, an arithmetic series is often used as a student's first example of a proof by mathematical induction. recall, from : mathematical induction is a method of mathematical proof typically used to establish a given statement for all natural numbers. it is done in two steps. the first. An arithmetic series is the sum of an arithmetic sequence, a sequence with a common difference between each two consecutive terms. base case: in an induction proof, the base case is the anchor step. it is the first domino to fall, creating a cascade and thus proving the statement true for every number greater than the base case. induction. Here we introduce a method of proof, mathematical induction, which allows us to prove many of the formulas we have merely motivated in sections 7.1 and 7.2 by starting with just a single step. a good example is the formula for arithmetic sequences we touted in theorem 7.1.1. arithmetic sequences are defined recursively, starting with a1 = a and.
