GEC

Finding the Odd Letter Cluster

The question asks us to identify the letter cluster that does not follow the same pattern as the others. We need to analyze the alphabetical order and the difference between consecutive letters in each cluster.

Letter Cluster Analysis

  • Option 1: UWY
    • U is the 21st letter.
    • W is the 23rd letter.
    • Y is the 25th letter.
    • Pattern: The difference between consecutive letters is \(+2\) ( \(21 \rightarrow 23\), \(23 \rightarrow 25\) ).
  • Option 2: OQS
    • O is the 15th letter.
    • Q is the 17th letter.
    • S is the 19th letter.
    • Pattern: The difference between consecutive letters is \(+2\) ( \(15 \rightarrow 17\), \(17 \rightarrow 19\) ).
  • Option 3: IKM
    • I is the 9th letter.
    • K is the 11th letter.
    • M is the 13th letter.
    • Pattern: The difference between consecutive letters is \(+2\) ( \(9 \rightarrow 11\), \(11 \rightarrow 13\) ).
  • Option 4: GEC
    • G is the 7th letter.
    • E is the 5th letter.
    • C is the 3rd letter.
    • Pattern: The difference between consecutive letters is \(-2\) ( \(7 \rightarrow 5\), \(5 \rightarrow 3\) ).

Identifying the Odd One Out

Options 1, 2, and 3 (UWY, OQS, IKM) consist of letters that are in increasing alphabetical order, with a gap of one letter between each consecutive letter (a difference of \(+2\)).

Option 4 (GEC) consists of letters that are in decreasing alphabetical order, with a gap of one letter between each consecutive letter (a difference of \(-2\)).

Therefore, GEC is the odd letter cluster out because it follows a decreasing pattern, unlike the others which follow an increasing pattern.
