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
SVZ

Analyzing Letter Cluster Patterns

The question requires identifying the letter-cluster that does not follow the same alphabetical pattern as the others. We need to examine the gaps between consecutive letters in each cluster based on their position in the English alphabet.

Letter Positions:

  • A=1, B=2, C=3, ..., Z=26

Cluster Analysis:

  1. CEJ
    • C is the 3rd letter.
    • E is the 5th letter.
    • J is the 10th letter.
    • Difference: E - C = $5 - 3 = 2$.
    • Difference: J - E = $10 - 5 = 5$.
    • Pattern: +2, +5
  2. GIN
    • G is the 7th letter.
    • I is the 9th letter.
    • N is the 14th letter.
    • Difference: I - G = $9 - 7 = 2$.
    • Difference: N - I = $14 - 9 = 5$.
    • Pattern: +2, +5
  3. PRW
    • P is the 16th letter.
    • R is the 18th letter.
    • W is the 23rd letter.
    • Difference: R - P = $18 - 16 = 2$.
    • Difference: W - R = $23 - 18 = 5$.
    • Pattern: +2, +5
  4. SVZ
    • S is the 19th letter.
    • V is the 22nd letter.
    • Z is the 26th letter.
    • Difference: V - S = $22 - 19 = 3$.
    • Difference: Z - V = $26 - 22 = 4$.
    • Pattern: +3, +4

Identifying the Odd Cluster

The letter-clusters CEJ, GIN, and PRW all share the pattern of adding 2, then adding 5 to the alphabetical position of the preceding letter. The cluster SVZ follows a different pattern (+3, +4). Therefore, SVZ is the cluster that does not belong to the group.
