1.1Patterns and Inductive Reasoning

Quick Answer

Inductive reasoning draws general conclusions from specific examples. A conjecture is a conclusion based on a pattern. A counterexample is one example that disproves a conjecture.

Essential Question

How does inductive reasoning help us form conjectures, and why is one counterexample enough to disprove a conjecture?

Learning Goals

  • 1Identify patterns in sequences and figures.
  • 2Make conjectures using inductive reasoning.
  • 3Find counterexamples to disprove conjectures.
  • 4Distinguish inductive from deductive reasoning.
