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).
20, 14, 8, =2 (sub 6 from each number).

6, 20, 8, 14, 10, 8, 12, .....What number should come next?
a1 b1 a2 b2 a3 b3 a4 b4(?) a5(?)
6 20 8 14 10 8 12
a1-a2= 6-8 =-2 Again, b1-b2=20-14=6
a2-a3= 8-10=-2 b2-b3=14-8 =6
a3-a4=10-12=-2 So, b3-b4=6=8-2*
So, a4-a5=-2=12-14*
Ans: Next numbers are b4=2 and a5=14.
a1 b1 a2 b2 a3 b3 a4 b4(?) a5(?)
6 20 8 14 10 8 12

a2-a3= 8-10=-2 b2-b3=14-8 =6
a3-a4=10-12=-2 So, b3-b4=6=8-2*

Ans: Next numbers are b4=2 and a5=14.

Its very simple.
Adding two with odd positioned numbers. (6+2=8, 8+2=10, 10+2=12, 12+2=14).
Subtracting six by even positioned numbers. (20-6=14, 14-6=8, 8-6=2).
So the answer is 2 14.

Alternating addition and subtraction series.
In the first pattern, 2 is added to each number.
In the second pattern, 6 is subtracted from each number. To arrive at the next.

Simply here in series 2 is added in odd positions and 6 is subtracted at even positions.
