GRU

Letter Series Reasoning: CNQ, DOR, EPS, FQT, ?

This question involves identifying a pattern in a sequence of letter clusters and determining the next cluster.

Pattern Analysis

Let's break down the series CNQ, DOR, EPS, FQT, ? by analyzing the position of each letter in the alphabet (A=1, B=2, ..., Z=26).

  • First Letter Progression:
    • C is the 3rd letter.
    • D is the 4th letter (3 + 1).
    • E is the 5th letter (4 + 1).
    • F is the 6th letter (5 + 1).
    • The next letter should be the 7th letter, which is G (6 + 1).
  • Second Letter Progression:
    • N is the 14th letter.
    • O is the 15th letter (14 + 1).
    • P is the 16th letter (15 + 1).
    • Q is the 17th letter (16 + 1).
    • The next letter should be the 18th letter, which is R (17 + 1).
  • Third Letter Progression:
    • Q is the 17th letter.
    • R is the 18th letter (17 + 1).
    • S is the 19th letter (18 + 1).
    • T is the 20th letter (19 + 1).
    • The next letter should be the 21st letter, which is U (20 + 1).

Conclusion

Combining the next letters for each position (G, R, U), the next cluster in the series is GRU.
