From the following question, in the given options, three options are similar in a certain pattern and one is different from the rest. Choose the option that is different from the rest.

1. A

   CGKO

2. B

   GILO

3. C

   BFJN

4. D

   EIMQ

Appeared in: CGHS SSC - 2018

Explanation

• The pattern in three of the options involves a consistent arithmetic progression in the alphabetical positions of the letters.
• In the option GILO, the letters are positioned at 7, 9, 12, and 15.
• The gaps between these positions are +2 (from G to I), +3 (from I to L), and +3 (from L to O).
• This non-uniform pattern of +2, +3, +3 makes it different from the other options, which all have a uniform +4 pattern.

Why Other Options Were Wrong

• Option A: This option follows the common pattern. The letters C(3), G(7), K(11), and O(15) have a consistent gap of +4 between them.
• Option C: This option follows the common pattern. The letters B(2), F(6), J(10), and N(14) have a consistent gap of +4 between them.
• Option D: This option follows the common pattern. The letters E(5), I(9), M(13), and Q(17) have a consistent gap of +4 between them.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identifying patterns in alphabetical series (Odd Man Out) as background academic context rather than a clinical decision trigger.
• This type of logical reasoning question assesses analytical and pattern-recognition skills, which are essential for nurses in clinical settings.
• Nurses use pattern recognition to identify trends in patient vital signs, interpret lab results, and recognize early signs of patient deterioration.
• What if? If the option was 'GJNQ', the pattern would be G(7) → J(10) → N(14) → Q(17), with gaps of +3, +4, +3. This would still be an irregular pattern, making it a potential odd one out depending on the other options.

How to Approach the Question

• First, understand the task: you need to find the one option that doesn't fit the pattern of the other three.
• Assign a numerical value to each letter based on its position in the alphabet (A=1, B=2, C=3, etc.).
• For each option, calculate the difference (the 'gap' or 'step') between the numerical values of consecutive letters.
• Compare the patterns of these gaps across all four options.
• The option with a unique or inconsistent pattern of gaps is the correct answer.
