N 1 Show that the given statement is true when n 1. 1 2 3 4 etc. Show that given any positive integer n n n3 2n n 3 2 n yields an answer divisible by 3 3.
For any natural numbers n and m n is less than or equal to m if and only if m is not less than n.
Here is a more reasonable use of mathematical induction. This statement can often be thought of as a function of a number n where n 123. Show that if any one is true then the next one is true. Show it is true for the first one.
