First select the alternate numbers.
6, 8, 10, 12, =14 (add plus 1).
20, 14, 8, =2 (sub 6 from each number).
6, 8, 10, 12, =14 (add plus 1).

First pattern numbers is 6,8,10,12
alternate pattern numbers is 20,14,8
FP is adding 2 with each num: 6+2=8, 8+2=10, 10+2=12, 12+2=14 so 14 is answer.
AP is sub 6 with each num: 20-6=14, 14-6=8, 8-6=2 so 2 is answer.
so the answer is 6 20 8 14 10 8 12 2 14
alternate pattern numbers is 20,14,8
FP is adding 2 with each num: 6+2=8, 8+2=10, 10+2=12, 12+2=14 so 14 is answer.
AP is sub 6 with each num: 20-6=14, 14-6=8, 8-6=2 so 2 is answer.
so the answer is 6 20 8 14 10 8 12 2 14
