Question

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster 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.)

The correct answer is
YAC

Analyze Alphabetical Patterns

The task is to find the letter cluster that is different from the others based on the English alphabetical order. Three clusters share a common pattern, while one does not.

Letter Positions in Alphabet

Assign numerical values to each letter (A=1, B=2, ..., Z=26).

  • YAC: Y=25, A=1, C=3
  • PRU: P=16, R=18, U=21
  • NPS: N=14, P=16, S=19
  • JLO: J=10, L=12, O=15

Calculate Letter Intervals

Determine the difference in alphabetical positions between consecutive letters. Consider the alphabet as circular (wrapping around from Z to A).

For YAC:
- From Y (25) to A (1): The interval is +2 (Y \(\rightarrow\) Z \(\rightarrow\) A). Calculation: \(26 - 25 + 1 = 2\).
- From A (1) to C (3): The interval is +2 (A \(\rightarrow\) B \(\rightarrow\) C). Calculation: \(3 - 1 = 2\).
Resulting pattern: +2, +2.

For PRU:
- From P (16) to R (18): Interval is +2. Calculation: \(18 - 16 = 2\).
- From R (18) to U (21): Interval is +3. Calculation: \(21 - 18 = 3\).
Resulting pattern: +2, +3.

For NPS:
- From N (14) to P (16): Interval is +2. Calculation: \(16 - 14 = 2\).
- From P (16) to S (19): Interval is +3. Calculation: \(19 - 16 = 3\).
Resulting pattern: +2, +3.

For JLO:
- From J (10) to L (12): Interval is +2. Calculation: \(12 - 10 = 2\).
- From L (12) to O (15): Interval is +3. Calculation: \(15 - 12 = 3\).
Resulting pattern: +2, +3.

Identify the Outlier Cluster

Three clusters (PRU, NPS, JLO) exhibit the interval pattern +2, +3.

The cluster YAC shows a different pattern, +2, +2.

Therefore, YAC is the letter cluster that does not belong to the group.
