Difficulty: Easy
Correct Answer: 1440
Explanation:
Introduction / Context:
This is a product-based series where each term is obtained by multiplying the previous term by a steadily increasing integer. Identifying the evolving multiplier lets us extend the series confidently.
Given Data / Assumptions:
Concept / Approach:
Compute term-wise ratios to the previous term. If the ratios form 2, 3, 4, 5, … then the next multiplier is 6. Apply that to get the missing term.
Step-by-Step Solution:
4 / 2 = 212 / 4 = 348 / 12 = 4240 / 48 = 5Next multiplier = 6 ⇒ Next term = 240 * 6 = 1440
Verification / Alternative check:
This pattern is strictly multiplicative with consecutive integers. No additive pattern fits all jumps so precisely (2→4→12→48→240), reinforcing the identified rule.
