Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair DOES NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster)

HL-JN

MU-KH

NR-PT

SW-UY

💡 Analysis & Explanation

Positional Shift Analysis ▼

We evaluate the alphabetical gaps between the letters in each pair.

Standard Pattern Verification ▼

In 'HL-JN', H(8) to L(12) is +4, J(10) to N(14) is +4, and the gap between the groups (L to J) is -2. This '+4, -2, +4' logic also perfectly applies to 'NR-PT' and 'SW-UY'.

Anomaly Detection ▼

In 'MU-KH', M(13) to U(21) is an +8 shift, which entirely breaks the established +4 sequential rule.

Conclusion ▼

Therefore, MU-KH is the odd pair out.
