Difficulty: Medium
Correct Answer: MQNRO
Explanation:
Introduction / Context:Each block has five letters, and every position within the block (1st through 5th) follows its own independent alphabetical rule across blocks. Two of these rules move forward by +3, and two move backward by −2, creating a braided pattern.
Given Data / Assumptions:
Concept / Approach:Write the five vertical streams: 1st letters, 2nd letters, 3rd, 4th, and 5th. Identify the step for each stream, then apply it to the last known block to generate the next block.
Step-by-Step Solution:
1st letters: A → D → G → J → M (each +3).2nd letters: Y → W → U → S → Q (each −2).3rd letters: B → E → H → K → N (each +3).4th letters: Z → X → V → T → R (each −2).5th letters: C → F → I → L → O (each +3).Combine: M Q N R O → MQNRO.Verification / Alternative check: Why Other Options Are Wrong: Common Pitfalls:Trying to spot a single across-the-line rule inside each block instead of tracking columns through successive blocks. Final Answer:MQNRO
