Difficulty: Easy
Correct Answer: 1440
Explanation:
Introduction / Context:
Product series frequently multiply by increasing integers. Detecting the multiplying factors allows quick prediction of the next term.
Given Data / Assumptions:
Concept / Approach:
Check ratios between successive terms: they may be 2, 3, 4, 5, suggesting the next ratio is 6. Such factorial-like growth is common in exam problems.
Step-by-Step Solution:
Verification / Alternative check:
List multipliers: 2, 3, 4, 5, 6. They form a simple ascending integer sequence, confirming the logic.
Why Other Options Are Wrong:
Common Pitfalls:
Assuming constant ratio. Here the ratio itself increases by 1 each step.
Final Answer:
1440
