WebYou do not try to prove the induction hypothesis. Now you prove that P(n+1) follows from P(n). In other words, you will use the truth of P(n) to show that P(n+ 1) must also be true. Indeed, it may be possible to prove the implication P(n) !P(n+1) even though the predicate P(n) is actually false for every natural number n. For example, suppose

WebIn calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms.
