Three-letter blocks with modular +6 shifts (mod 26): ajs, gpy, ?, sbk, yhq Find the missing triplet by tracking each character’s independent progression.

Introduction / Context:
This pattern-recognition problem uses blocks of three letters. Each position within the triplet (1st, 2nd, 3rd) follows its own arithmetic progression around the alphabet. We extend those position-wise rules using modular arithmetic (wrapping after Z→A).

Given Data / Assumptions:

• Triplets: ajs, gpy, ?, sbk, yhq
• Alphabet indices: a=1, …, z=26.
• Progressions may wrap around at 26 (modulo 26 arithmetic).

Concept / Approach:
Split the sequence into three independent letter streams: all first letters, all second letters, and all third letters. Determine each stream’s rule (increment per step), then compute the missing letters.

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

• dmv, oua, qzi each break at least one of the +6 mod 26 streams (first, second, or third letter sequence).

Common Pitfalls:
Trying to relate letters across a triplet instead of tracking each column separately, or forgetting to wrap beyond Z using modulo arithmetic.
