Difficulty: Easy
Correct Answer: YXW
Explanation:
Introduction / Context:This is a descending triplet pattern with the starting letter increasing by 2 each step while letters inside each triplet descend by 1.
Given Data / Assumptions:
Concept / Approach:Track the first letters: Q, S, U, W → each +2 steps → next is Y. Then build a descending triple starting from Y.
Step-by-Step Solution:First letters: Q → S (+2) → U (+2) → W (+2) → Y (+2).Triplet for Y: Y, X, W (each −1).
Verification / Alternative check:All previous triplets obey the same structure; continuing yields YXW uniquely.
Why Other Options Are Wrong:
Common Pitfalls:Forgetting that the inner order is always descending by 1 from the first letter.
Final Answer:YXW
