Odd positions:
6, 8, 10, 12 , y→ clearly +2 pattern --> y = 12+2 = 14.
Even positions:
20, 14, 8, x → -6 decreasing pattern --> x = 8-6 = 2.
6, 8, 10, 12 , y→ clearly +2 pattern --> y = 12+2 = 14.
Even positions:
20, 14, 8, x → -6 decreasing pattern --> x = 8-6 = 2.

The logic is;
6, 8, 10, 12, 14. Is in even positions. Add +2.
20, 14, 8, 2. Is in odd positions. So, Sub-6.
6, 8, 10, 12, 14. Is in even positions. Add +2.
20, 14, 8, 2. Is in odd positions. So, Sub-6.

It's really confusing series, but we take even series in increasing and decreasing order separately.
Even series taken in increasing order 6 8 10 12.
Even series taken in decreasing order 20 14 8.
We see that increasing series increases by 2 and decreasing series decreases by 6. So the last two digit will be 14 in increasing series and 2 will be in decreasing series.
Even series taken in increasing order 6 8 10 12.
Even series taken in decreasing order 20 14 8.
We see that increasing series increases by 2 and decreasing series decreases by 6. So the last two digit will be 14 in increasing series and 2 will be in decreasing series.

6 20 8 14 10 8 12 2 14.
1) 20-6 = 14.
14-6 = 8.
8-6 = 2.
2) 6+2 = 8.
8+2 = 10.
10+2 = 12.
12+2 = 14.
1) 20-6 = 14.
14-6 = 8.
8-6 = 2.
2) 6+2 = 8.
8+2 = 10.
10+2 = 12.
12+2 = 14.
