6+2 = 8.
8+2 = 10,
10+2 = 12,
12+2 = 14.
20-6 = 14,
14-6 = 8,
8-6 = 2.
So, the Answer is 2 14.
6+2 = 8.
8+2 = 10,
10+2 = 12,
12+2 = 14.
20-6 = 14,
14-6 = 8,
8-6 = 2.
So, the Answer is 2 14.

Each element in the even position is the resultant of a multiple of 2 starting from 3 i.e 2*3=6, 2*4=8, 2*5=10, 2*6=12, so at position 8, 2*7=14.
Each element in the odd position is also the result of multiples of 2 starting from 10 with a decrement of 3 each time i.e. 2*10=20, 2*7=14, 2*4=8 so now at position 7, we need to decrement 4 by 3 i.e 4-3=1 and multiply with 2 i.e. 2*1=2.
So our answer is 2,14

6 20 8 14 10 8 12.
6 + 2 = 8.
8 + 2 = 10.
10 + 2 = 12.
20 - 6 = 14.
14 - 6 = 8,
So, that 8 - 6 = 2.
6 + 2 = 8.
8 + 2 = 10.
10 + 2 = 12.
20 - 6 = 14.
14 - 6 = 8,
So, that 8 - 6 = 2.

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
