Answer
Correct Answer: (18, 30, 42)
Explanation
Introduction / Context:(12, 20, 28) forms an arithmetic progression with common difference +8. We need a triple that is also an arithmetic progression with a constant difference (not necessarily +8, but consistent).
Concept / Approach:Check options: (18, 30, 42) has +12 and +12, so it mirrors the AP structure.
Why Other Options Are Wrong:They do not maintain a constant difference throughout.
Final Answer:(18, 30, 42)
