Show that if any one is true then the next one is true. Mathematical induction is a method of mathematical proof typically used to establish a given statement for all natural numbers. Proof by mathematical induction.
The first step known as the base case is to prove the given statement for the first natural number.
An example of the application of mathematical induction in the simplest case is the proof that the sum of the first n odd positive integers is n 2 that is that 1 1 3 5 2n 1 n 2 for every positive integer n. Show it is true for the first one. Is there too little information given about set A itself. How would I go about writing a proof for this question.
