Question

What number will replace the question mark?

Hint:

For numerical pattern problems, identify operations (e.g., multiplication, addition) between numbers systematically and test the relationship row by row.

Answer 1

Step 1: Analyze the pattern in the given rows.
Each row follows a relationship where the product of the first two numbers equals the third number in the row.
Step 2: Verify the pattern for the first two rows.
For the first row: \[ 2 \times 4 = 8, \quad \text{and } 12 = 8 \times 1.5. \] For the second row: \[ 10 \times 5 = 50, \quad \text{and } 75 = 50 \times 1.5. \]
Step 3: Apply the pattern to the last row to find the missing number.
For the third row: \[ 12 \times 9 = 108, \quad \text{and } ? = 108 \times 1.5 = 162. \]
Step 4: Conclude the answer.
The number replacing the question mark is:
{162}.
