Question

What number should replace the question mark?

• A. 1
• B. 4
• C. 12
• D. 6

Answer 1

The Correct Option is D

To solve the problem, we observe the pattern within the given set of numbers. The sequence appears in the form of a square matrix. The common technique in such puzzles is to look for relationships between rows, columns, or diagonals.
 
Upon inspection, there appears to be a pattern related to multiplication and subtraction that we can identify by analyzing each row:
1. **First Row (2, 4, 6):**
Starting with the first number, (2 × 2) - 2 = 4. Check: (4 × 2) - 2 = 6.
2. **Second Row (3, 5, 7):**
Following the same pattern, (3 × 2) - 1 = 5. Check: (5 × 2) - 3 = 7.
3. **Third Row (4, 6, ?):**
Applying the identified pattern: (4 × 2) - 2 = 6. Hence, the missing number is:
(6 × 2) - 6 = 6.

This indicates that each row follows the relationship of multiplying the first number by 2, then subtracting a defined value. Upon confirmation, the missing number should be 6.

The analysis of the puzzle reveals a consistent pattern across the matrix helping us identify the number that replaces the question mark is 6.
