Inductive Reasoning and Conjectures in Geometry

The video tutorial introduces inductive reasoning, using examples to illustrate how patterns can be identified and conjectures formed. It begins with a number series, exploring potential patterns and defining conjectures as unproven statements. The tutorial explains how inductive reasoning is used to predict the next terms in a series and applies this reasoning to a shape pattern. The video concludes with a brief mention of proving conjectures in future content.

What is the best way to understand inductive reasoning?

• By memorizing definitions

• By jumping straight into an example

• By reading a textbook

• By watching a movie

What is the pattern in the series -7, -21, -63, -1889?

• Multiplying by 3 each time

• Dividing by 2 each time

• Adding 7 each time
