Difficulty: Easy
Correct Answer: 27
Explanation:
Introduction / Context:
Many number series use alternating operations. Recognizing the repeating pattern (multiply by a constant, then divide by a constant) allows quick continuation of the sequence.
Given Data / Assumptions:
Concept / Approach:
Compare each transition: 8 to 24 appears as ×3, then 24 to 12 as ÷2. If this alternates, the pattern is ×3, ÷2, ×3, ÷2, and so on.
Step-by-Step Solution:
Verification / Alternative check:
Continue one more step mentally to ensure consistency: after 27, the next would be ×3 → 81, reinforcing the alternating structure.
Why Other Options Are Wrong:
Common Pitfalls:
Applying the wrong operation order (e.g., dividing when multiplication is due). Always map the full alternating pattern before computing the next term.
Final Answer:
27
