Take the no's in even positions is the increasation of 2, and in odd positions no's is in decresing order of 6.
6, 8, 10, 12, 14.... is in even positions.
20, 14, 8, 2.... is in odd positions.
6, 8, 10, 12, 14.... is in even positions.

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
