Show answer & explanation
Correct answer: B
1. Analyze the mathematical relationship between consecutive numbers in the series.
2. Notice the division pattern: 5040 ÷ 6 = 840; 840 ÷ 5 = 168.
3. Following this pattern of dividing by sequentially decreasing numbers, the next step is 168 ÷ 4 = 42.
4. Checking the rest of the series confirms the logic: 42 ÷ 3 = 14, and 14 ÷ 2 = 7.
Final Answer: Option B
