Determine the value that should replace the question mark in the following number sequence:
12, 48, 24, 96, ?, 192
Correct Answer :
48
Solution :
Correct Answer: The correct option is 48.
To find the missing number in the sequence, let us analyze the pattern or rule that connects consecutive terms in the series:
12, 48, 24, 96, ?, 192
Let us look at the operations between consecutive numbers step-by-step:
Step 1: Transition from 1st number (12) to 2nd number (48):
Step 2: Transition from 2nd number (48) to 3rd number (24):
Step 3: Transition from 3rd number (24) to 4th number (96):
From the steps above, we observe an alternating pattern of operations:
First multiply by 4 (), then divide by 2 ().
Step 4: Apply the next operation () to the 4th number (96) to find the missing number (?):
Step 5: Verify the pattern with the final number (192) by multiplying the result by 4 ():
Since this matches the last term in the sequence, the value that replaces the question mark is indeed 48.
