Difficulty: Medium
Correct Answer: 24
Explanation:
Introduction / Context:
Some series apply successive divisions by decreasing even numbers (e.g., ÷12, ÷10, ÷8, ÷6, ÷4, ÷2). A single mis-division yields a standout term. Here we test that descending-divisor hypothesis.
Given Data / Assumptions:
Concept / Approach:
Check each step against the intended divisor chain. Where the quotient disagrees, the respective term is wrong. After correction, later terms should follow smoothly.
Step-by-Step Solution:
46080 ÷ 12 = 3840 ✓3840 ÷ 10 = 384 ✓384 ÷ 8 = 48 ✓Next should be 48 ÷ 6 = 8 (but given: 24 ✗)Then 8 ÷ 4 = 2, and 2 ÷ 2 = 1 ✓
Verification / Alternative check:
Once 24 is replaced by 8, the chain becomes perfectly coherent with divisors 12, 10, 8, 6, 4, 2. The final terms (2, 1) already match the intended finishing steps.
