This video tutorial teaches how to determine rules in decreasing number patterns using tables. It begins with an introduction to patterns and their rules, emphasizing that not all patterns increase. The lesson explains how tables can help organize patterns and prevent mistakes. It also covers analyzing complex patterns, showing how the amount subtracted decreases as steps increase. The tutorial concludes by highlighting the importance of tables in identifying and verifying pattern rules.

What is the rule in the pattern 15, 13, 11, 9?

• Subtract 2

• Subtract 3

• Subtract 4

• Subtract 1

Why is it important to use a table when analyzing patterns?

• To add more numbers to the pattern

• To make the pattern look neat

• To organize the pattern and avoid mistakes

• To ensure the pattern is increasing
