Answer :
Answer:
- 100; 80, 60, 40
- 20; 16, 12, 8
- dividing by 5
Step-by-step explanation:
You want to fill a table using the given rules, then describe the relationship between the table values.
Pattern A
Starting with 100, you want to subtract 20 to get next terms:
100
100 -20 = 80
80 -20 = 60
60 -20 = 40
The next terms are 80, 60, 40.
Pattern B
Starting with 20, you want to subtract 4 to get next terms:
20
20 -4 = 16
16 -4 = 12
12 -4 = 8
The next terms are 16, 12, 8.
Relationship
Looking at second terms, we can determine which description is true:
80 -80 = 0 ≠ 16 . . . . . the description "subtract 80" fails
80/5 = 16 . . . . . . . . . . the description "divide by 5" works
Each term in pattern B can be found by dividing the corresponding term in pattern A by 5.
