Mathematical Induction

Mathematical induction is a proof technique used to establish that a property holds for all natural numbers. It works by showing that if the property is true for a starting case (usually n = 1), and if assuming it is true for an arbitrary number n allows one to prove it for n+1, then the property holds for all natural numbers.

Base Case

The base case is the first step in an inductive proof. It involves checking that the statement is true for the initial value, often n = 1. This step establishes the validity of the statement that the induction will build upon.

Inductive Hypothesis

The inductive hypothesis is the assumption that the statement under consideration is true for an arbitrary natural number n. This assumption is a temporary step used to demonstrate that, under this hypothesis, the statement must also be true for the next integer, n+1.

Inductive Step

The inductive step involves showing that if the statement holds for some arbitrary natural number n (as assumed in the inductive hypothesis), then it must also hold for n+1. This step is crucial as it creates a chain linking each case to the next, thereby proving the statement for all natural numbers.

Arithmetic Series

An arithmetic series is the sum of the terms of an arithmetic sequence, where each term increases by a constant difference. Recognizing an arithmetic series, such as the sequence given by 1, 4, 7, ..., (3n-2), allows one to set up a formula for its sum. Proving the correctness of this formula via mathematical induction connects the concept of sequences and series with proof techniques.
