  1. How do you find the rule in a reducing pattern? For example: Find the Rule. What are the next 4 steps: 50, 40, 31, 23, 16…..

  2. In this lesson you will learn about determining the rule in patterns that decrease by using a table.

  3. Steps and Rules Step 1 Step 2 Step 3 Step 4 Step 7 15, 13, 11, 9….. RULE -2 -2 -2 -2

  4. When finding the rule in a pattern, don’t assume all patterns increase. 18, 15, 12, 9 ... -3 -3 -3 -3

  5. Use a table to check for the rule being used on the pattern. Step 1 18, 15, 12, 9 ... RULE -3 -3 -3 -3 6 3 0 -3 -3 -3 -3 -3 -3 -3

  6. Find the rule: 50, 40, 31, 23, 16… -10 -9 -8 -7 RULE 10 5 1 Step4 -7 Step5 -6 Step7 -4 Step1 -10 Step2 -9 Step3 -8 Step6 -5 As the step increases, the amount subtracted reduces.

  7. Inthis lesson you learned about finding the rule for decreasing patterns by using a table.

  8. Find the rule. Find the next 3 numbers 33, 28, 23, 18….. -5 -5 -5 -5 RULE 13 8 3 step6-5 step2-5 step3-5 step4-5 step5-5 step1-5

  9. Find the 7th number. • 50, 48, 46, 44… • Describe how you solved for the 7th step number.

  10. Find the next four numbers in the pattern. • 42, 36, 30, 24…

  11. What is the the next number in the pattern? 12, 10, 8, 6… A) 2 B) 16 C) 20 D) 4 What are the next two numbers in this pattern? 100, 90, 81, 73…. A) 70, 80… B) 66, 65… C) 66, 60 D)55, 20
