Answer
Correct Answer: MQN
Explanation
Introduction / Context:Two-step signatures are common in short triples. If most items jump forward by 3 and then back by 2, the remaining item will be the one with different magnitudes.
Given Data / Assumptions:
- HKI: H→K (+3), K→I (−2) → fits.
- UXV: U→X (+3), X→V (−2) → fits.
- CFD: C→F (+3), F→D (−2) → fits.
- MQN: M→Q (+4), Q→N (−3) → does not fit.
Concept / Approach:Compute differences and compare to the template (+3, −2). The sole deviation flags the odd item.
Step-by-Step Solution:
1) Convert letters to indices.2) Check for +3 then −2.3) MQN yields +4 then −3 → outlier.Verification / Alternative check:Reversing the direction keeps MQN misaligned, confirming it as the odd one.
Why Other Options Are Wrong:They satisfy the exact two-step signature.
Common Pitfalls:Do not overlook sign; both magnitude and sign matter.
Final Answer:MQN
