Theorem 1.3.1 (Principle of Mathematical Induction: Strong Form). Let P(n) be a statement As the first step of the induction hypothesis, we see that R(1) holds true (already assumed the proof technique “disproving by counter-example”.

Some typical examples are shown below. Example 2.2. Prove that 23 1 n − is divisible by 11 for all positive integers n. 2. Induction Examples. † The Principle of Mathematical Induction. Suppose we have some statement PHnL and we want to demonstrate that PHnL is true for all. Mathematical induction is a special method of proof used to prove statements about all the natural numbers. For example,. "n- n is always divisible by 3". Notice that the example we cooked up above fails (P5), since in [0, ∞) the subset of natural numbers contains zero and contains the successor of each of its  6. Mathematical Induction I. The following example shows how to use mathematical induction to prove a formula for the sum of the first n integers.

▫ In the book there is a similar example. Induction and Recursion. ▫ Induction is useful for proving correctness/ design of recursive algorithms.

Chapter 2. Mathematical Induction. 2.1 First Examples. Suppose we want to find a simple formula for the sum of the first n odd numbers: 1+3+5+ + (2n − 1) = n. For example P might stand for the proposition: 'humans will land on mars by 2005 '. le propositions. Page 3. Much of mathematics is concerned with establishing  Induction Introduction.
