Factor mathematical induction. 2, Example 5.
Factor mathematical induction. This reasoning is very useful when studying number patterns. Quick Aside This result helps explain the range of numbers that can be stored in an int. Example 3 Without adding, determine if 7 a factor of 49 + 70. 2, Example 5. In many situations, inductive reasoning strongly suggests that the statement is valid, however, we have no way to present whether the statement is true or false, for example 27 MATHEMATICAL INDUCTION The principle of mathematical induction T HE NATURAL NUMBERS are the counting numbers: 1, 2, 3, 4, etc. Therefore we have shown thatx-yis a factor ofxn-ynfor all positive integersn. By "every", or "all," natural numbers, we mean any one that we name. To see the logical need for mathematical induction, take another look at the problem discussed in Section 8. Mathematical Induction is a special way of proving things. Introduction Mathematical induction is a method that allows us to prove in nitely many similar statements in a systematic way, by organizing them all in a de nite order and showing the rst statement is correct (\base case") if a particular but unspeci ed statement in the list is correct (\inductive hypothe-sis"), then the statement after it in the list is correct (\inductive step"). osc rcfo q3yckm 4ux qzfopz jrcuxg zh2wber reyzam 4ud5i 9i
