Question

What is the missing value

Answer 1

Answer: 
108

Explanation:
To find a missing number in a sequence, find the relation between all the numbers. If you look at 4 and then twelve, there are two ways you can get from 4 to 12. 
4 + 8 
or 
4 • 3. 
Now see if when you add eight to 12 you get to 36. 
12 + 8 = 20 
This doesn't work, so try multiplying by 3. 
12 • 3 = 36 
Yes! So this must be the rule for all the numbers. 
36 • 3 = 108 so that is the missing number. 
To check to see if you are right, multiply 108 by three to get 324, the next number in the sequence.
