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…..
In this lesson you will learn about determining the rule in patterns that decrease by using a table.
Steps and Rules Step 1 Step 2 Step 3 Step 4 Step 7 15, 13, 11, 9….. RULE -2 -2 -2 -2
When finding the rule in a pattern, don’t assume all patterns increase. 18, 15, 12, 9 ... -3 -3 -3 -3
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
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.
Inthis lesson you learned about finding the rule for decreasing patterns by using a table.
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
