Inductive Reasoning and Conjectures Challenge

This video tutorial introduces inductive reasoning, focusing on identifying patterns and making conjectures. It explains how to use examples to form conjectures and how to find counter examples to disprove them. The lesson includes practical examples with numbers, patterns, and real-world data, such as whale sizes, to illustrate these concepts.

What is the next month in the pattern: January, March, May?

• August

• September

• July

• June

If a pattern in numbers starts with 7, 14, 21, what is the next number?

• 30

• 28

• 42

• 35
