Answer:
54 is the missing number.
__________________________
Step by step explanation:
12-9=3
18-12=6
30-18=12
since, everytime the difference between two numbers get double.
so, double of 12 will be 24
therefore, 30+ 24=54
difference between 54 and 102 should be double of 24 i.e 48
= 102-54= 48.
Hence, the missing number is 54.

The missing number is 54.
Explanation:
Given: 9, 12, 18, 30, ____, 102
The difference between the first two numbers are 12 - 9 = 3.
Next two numbers are 18 - 12 = 6.
Then 30 - 18 = 12.
So, the numbers are getting doubled by subtracting the numbers.
3, 6, 12, .... obviously the next number will be in the series 24.
Therefore, 30 + 24 = 54 is the missing number.
