Question

What number should replace the question mark in the image below?

• A. 18
• B. 20
• C. 22
• D. 24

Hint:

Compare each bottom number to the top number in the same column to spot the constant multiplying factor.

Answer 1

The Correct Option is D

Step 1: Read the two rows in the image.
Top row: 6, 12, ?. Bottom row: 48, 96, 192. Each bottom number sits below a top number, so check how they relate in the same column.

Step 2: Test the relationship in the first two columns.
Column 1: \(6 \times 8 = 48\). Column 2: \(12 \times 8 = 96\). Both columns confirm the bottom number is 8 times the top number.

Step 3: Apply the same rule to column 3.
The bottom number is 192, so the top number \(y\) must satisfy \[ y \times 8 = 192 \] \[ y = \frac{192}{8} = 24 \]

Step 4: Check the other options.
Option A (18) times 8 gives 144, option B (20) times 8 gives 160, option C (22) times 8 gives 176. None of these equal 192, only 24 does.

Final Answer:
The missing number is 24. \[ \boxed{24} \]
