Here the next term is twice the previous term like 24 is just twice of 12 and 36 just twice of 18 so 54 is just twice of 27 so answer is 27.

8*3 = 24%2 = 12;
12*3 = 36%2 = 18;
18*3 = 54%2 = 27;
So answer is 27.
8*3 = 24%2 = 12;
12*3 = 36%2 = 18;
18*3 = 54%2 = 27;
So answer is 27.

It's so easy just see if 2nd digit comes in 1st digit table and then keep same series for other numbers. For example 24 comes in table of 8 so 8 into 3 will be 24. If we divide 24/2 then it will be 12. If 12 multiplied by 3 then it will be 36. 36 divide by 2 it will become 18. 18 multiplied by 3 will be 54. 54/2 will be 27. So answer will be 27.

We can take 2 series.
8, 12, 18, 26 with 4, 6, 8 differences.
24, 36, 54, 78 which is multiple of 3 for above terms?

8*3=24, 24/2=12.
12*3=36, 36/2=18.
18*3=54, 54/2=27.
27 is the right answer.
12*3=36, 36/2=18.
18*3=54, 54/2=27.
27 is the right answer.
