Question

Which one will replace the question mark (?)?

• A. 40
• B. 43
• C. 44
• D. 45

Answer 1

The Correct Option is B

Solution: Observing the pattern in the first two triangles, we can deduce a rule to find the central number based on the surrounding numbers.
1. In the first triangle: - Numbers: 5, 6, and 4 - The central number (34) can be calculated
\(5 × 6 + 4 = 30 + 4 = 34\)

2. In the second triangle: - Numbers: 9, 2, and 8 - The central number (26) can be calculated as:

\(9 × 2 + 8 = 18 + 8 = 26\)

Following the same pattern in the third triangle: - Numbers: 7, 6, and 3 - The missing central number (?) is calculated as:

\(7 × 6 + 3 = 42 + 3 = 45\)

Thus, the correct answer is 45.
