Mathematical induction is a critical proof technique in mathematics, akin to a domino effect, used to establish the truth of statements for all natural numbers. It involves verifying a base case, assuming an inductive hypothesis, proving an inductive step, and concluding the statement's validity. This method is essential for proving divisibility, inequalities, and validating formulas like the sum of square numbers and Binet's Formula for Fibonacci numbers.

Mathematical induction is a powerful proof technique that uses the analogy of falling dominoes to prove statements for all natural numbers
Base Case
The first step of mathematical induction is to verify the base case, which confirms the statement's validity at the starting point
Inductive Hypothesis
The second step is to assume the statement's truth for a generic case, known as the inductive hypothesis
Inductive Step
The third step involves proving that the truth of the statement for one case implies its truth for the next case
Mathematical induction is a versatile technique used to prove various mathematical propositions, including those concerning divisibility, inequalities, and sequences
Mathematical induction can be used to prove statements about divisibility, such as showing that an expression is divisible by a number for all natural numbers
Induction can also be used to prove inequalities, such as showing that a given expression is valid for an entire range of values
Strong induction is a form of mathematical induction that assumes the truth of the statement for all cases up to a certain value, rather than just for that value
Mathematical induction can be used to prove formulas, such as the formula for the sum of the first n square numbers
Induction is also useful for proving theorems, such as the Fundamental Theorem of Arithmetic, which asserts that every integer greater than 1 is uniquely factorable into prime numbers
Binet's Formula, which provides an explicit expression for the nth Fibonacci number, can be validated using induction
