Show answer & explanation
Correct answer: A
Solution: determine the pattern for each row.
Row 1: 3 × 4 × 2 = 24; add the first number 3 → 24 + 3 = 27
Row 2: 6 × 5 × 1 = 30; add the first number 6 → 30 + 6 = 36
Rule: the number at the end of each row = (product of the three row numbers) + (the first number of that row).
Apply to Row 3: 9 × 1 × 2 = 18; add the first number 9 → 18 + 9 = 27
Conclusion: The missing number should be 27 according to the consistent rule. Note: none of the given answer choices list 27, and the dataset's marked correct option (36) does not match the missing cell for the third row; 36 is the result for the second row under this rule.
