The logic is taking the alternate no. to form a series then we will get two series
1st is : 8,22,28,...
2nd is : 20,20.. which is constant
for first series the logic is 8,8*2+4,8*3+4,....and so on.

22-8 = 14

28-22=6

14-6=8

26-28= -2

6-(-2)=8

every time the difference is reduced by 8 so answer would be 26.

Make pairs of 2 and observe that 20 is repeating alternately.
(8,20) now add 2 in 20 (22,20) now add 8 in 20 (28,20) now add multiply of 2 and 8 i.e 16 (36,20)
Ans is 36

answer 22:
8 , 20 , 22 , 20 , 28 ,20,

difference: (20-8)==>12
> (12-2)==>10
(22-20)==>2
>(2-2)==>0
(20-22)==>-2
>(8+2)==>10
(28-20)==>8
>(8-8)==>0
(20-28)==>-8
>(2+8)==>10
(22-20)==>2
therefore 22 hope you found the pattern
