In the given series, the terms are arranged based on a certain principle. From the given options, select the missing term (represented by ?) based on the same principle. AAZY, DDVU, GGRQ, ?, MMJI, PPFE

Appeared in: CGHS SSC - 2018

Explanation

The pattern for the first and second letters in each term is to advance by 3 positions in the alphabet (A → D → G → J).
The pattern for the third letter is to go backward by 4 positions (Z → V → R → N).
The pattern for the fourth letter is also to go backward by 4 positions (Y → U → Q → M).
Applying these rules to the term after 'GGRQ', we get G+3=J, G+3=J, R-4=N, and Q-4=M.
Combining these letters results in the term 'JJNM'.

Option B: This option incorrectly identifies the first two letters as 'K' and the last two as 'M'. The pattern is +3 for the first two letters (G+3=J, not K) and -4 for the last two (R-4=N, Q-4=M).
Option C: This option incorrectly identifies the first two letters as 'K'. The established pattern is an increment of +3, which makes the next letters 'J' (G+3), not 'K' (G+4).
Option D: This option incorrectly identifies the first two letters as 'M' and reverses the last two letters. The pattern is +3 for the first two letters (G+3=J, not M) and the order for the last two is N, M, not J, N.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Letter Series as background academic context rather than a clinical decision trigger.
This question assesses logical and sequential reasoning skills.
While not directly clinical, these cognitive abilities are essential for nurses in tasks like interpreting patient data trends, following multi-step protocols, and making sound clinical judgments under pressure.
What if the pattern was alternating, such as +3, -4, +3, -4 for each position? The nurse's ability to detect complex patterns is analogous to recognizing subtle changes in a patient's condition over time.

How to Approach the Question

First, analyze the relationship between the first letters of each term in the series (A, D, G, ?, M, P).
Determine the pattern by finding the difference in alphabetical position (e.g., D is 3 letters after A).
Repeat this process for the letters in the second, third, and fourth positions independently.
Note that the pattern might be different for different positions (e.g., addition for the first two, subtraction for the last two).
Once you have identified the pattern for each of the four positions, apply it to the last known term ('GGRQ') to find the letters of the missing term.
Combine the resulting letters to form the final answer and match it with the given options.
