Reasoning for Alphabetical Order Logic

The question requires identifying the letter group that differs from the others based on alphabetical sequence rules. The note clarifies that vowel/consonant counts or positions are not the basis for this pattern.

Analyzing Letter Group Patterns

We assign numerical values to letters (A=0, B=1, ..., Z=25) and calculate the steps between consecutive letters using modulo 26 arithmetic.

• Option 1: DZA
  Positions: D(3), Z(25), A(0).
  Steps: D $\to$ Z is $(25 - 3) \mod 26 = 22$.
  Steps: Z $\to$ A is $(0 - 25) \mod 26 = 1$.
  Pattern: (22, 1)
• Option 2: CYZ
  Positions: C(2), Y(24), Z(25).
  Steps: C $\to$ Y is $(24 - 2) \mod 26 = 22$.
  Steps: Y $\to$ Z is $(25 - 24) \mod 26 = 1$.
  Pattern: (22, 1)
• Option 3: MJK
  Positions: M(12), J(9), K(10).
  Steps: M $\to$ J is $(9 - 12) \mod 26 = -3 \mod 26 = 23$.
  Steps: J $\to$ K is $(10 - 9) \mod 26 = 1$.
  Pattern: (23, 1)
• Option 4: EAB
  Positions: E(4), A(0), B(1).
  Steps: E $\to$ A is $(0 - 4) \mod 26 = -4 \mod 26 = 22$.
  Steps: A $\to$ B is $(1 - 0) \mod 26 = 1$.
  Pattern: (22, 1)

Identifying the Outlier

The letter groups DZA, CYZ, and EAB exhibit a consistent pattern of sequential steps (22, 1).

The group MJK follows a different pattern with steps (23, 1).

Therefore, MJK is the letter group that does not belong to the identified pattern.
