1) Pattern A starts at 20 and has the rule "subtract 2". Pattern B starts at 20 and has the rule "subtract 1". Which shows the first several terms of Patterns A and B?
Pattern A: 20, 22, 24, 26, 28, 30
Pattern B: 20, 21, 22, 23, 24, 25
Pattern A: 20,18,16, 14, 12, 10
Pattern B: 20, 21, 22, 23, 24, 25
Pattern A: 20,18.16.14, 12, 10
Pattern B: 20,19,18,17.16.15
Pattern A: 20. 17.15, 13.11,9
Pattern B: 20, 19.18, 17, 16.15

PA: 20, 18, 16, 14, 12, 10

PB: 20, 19, 18, 17, 16, 15

(Pair 3)

Step-by-step explanation:

We need to look for a pair with both sides decreasing.

Pair 1 has the exact opposite of what we need happening. It has the sides increasing, so it is out.

Pair 2 has the Pattern A right, but Pattern B is still going up, so it is also out.

Pair 4 has both sides decreasing but the second term on Pattern A is 3 less than the first term when it should be 2. As a result it is also out.

This leaves Pair 3 as our final answer.
