Analyzing Decreasing Patterns with Tables: Finding the Rule

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

In the pattern 18, 15, 12, 9, what is the rule?

• Subtract 4

• Subtract 3

• Subtract 2

• Subtract 5

What happens to the amount being subtracted in the complex pattern as the steps increase?

• It increases

• It stays the same

• It decreases

• It doubles

In the complex pattern, what is the rule for step 5?

• Subtract 8

• Subtract 5

• Subtract 7

• Subtract 6

How does the table help in identifying mistakes in the pattern?

• By highlighting incorrect numbers

• By showing the correct rule

• By adding extra steps

• By organizing the steps and rules clearly

What is the final step value in the complex pattern?

• 1

• 2

• 0

• 3
