1.1 Patterns and Inductive Reasoning Chapter 1 Tools of Geometry
Inductive Reasoning: reasoning based on patterns you observe Conjecture: conclusion you reach using inductive reasoning Counterexample: an example that proves the conjecture wrong
Finding and Using a Pattern Find a pattern for each sequence. Use the pattern to show the next two terms in the sequence. • 3, 6, 12, 24, … b.
Finding and Using a Pattern Write the next two terms in each sequence: a. 1, 2, 4, 7, 11, 16, 22, … b. Monday, Tuesday, Wednesday,…
Using Inductive Reasoning Make a conjecture about the sum of the first 30 odd numbers: 1 = 1 = 12 1 + 3 = 4 = 22 1 + 3 + 5 = 9 = 32 1 + 3 + 5 + 7 = 16 = 42 1 + 3 + 5 + 7 + 9 = 25 = 52 1 + 3 + 5 + 7 + 9 + 11 = 36 = 62 Make a conjecture about the first 35 odd numbers.
Testing a Conjecture Give a counterexample: The product of 5 and any number ends in 5. The sum of two numbers is greater than either number. Look in book at example 4, pg 6
