Analyzing Letter Pairs in Alphabetical Order

The question asks us to identify which pair of letter clusters is different from the others based on a pattern related to the English alphabetical order. We need to find the 'odd one out' among the given pairs. The note clarifies that the pattern isn't about vowels, consonants, or their positions within a cluster, but rather the relationship between the pairs themselves.

Step-by-Step Analysis of Pairs

Let's examine each pair by looking at the alphabetical position of each letter:

Pair 1: FK-IN

• F is the 6^th letter, K is the 11^th letter.
• I is the 9^th letter, N is the 14^th letter.
• Comparing the first letters: F (6) to I (9). The difference is \(9 - 6 = 3\).
• Comparing the second letters: K (11) to N (14). The difference is \(14 - 11 = 3\).
• Pattern: The letters in the second cluster (IN) are 3 positions after the corresponding letters in the first cluster (FK).

Pair 2: DI-GL

• D is the 4^th letter, I is the 9^th letter.
• G is the 7^th letter, L is the 12^th letter.
• Comparing the first letters: D (4) to G (7). The difference is \(7 - 4 = 3\).
• Comparing the second letters: I (9) to L (12). The difference is \(12 - 9 = 3\).
• Pattern: The letters in the second cluster (GL) are 3 positions after the corresponding letters in the first cluster (DI).

Pair 3: LP-NR

• L is the 12^th letter, P is the 16^th letter.
• N is the 14^th letter, R is the 18^th letter.
• Comparing the first letters: L (12) to N (14). The difference is \(14 - 12 = 2\).
• Comparing the second letters: P (16) to R (18). The difference is \(18 - 16 = 2\).
• Pattern: The letters in the second cluster (NR) are 2 positions after the corresponding letters in the first cluster (LP).

Pair 4: QV-TY

• Q is the 17^th letter, V is the 22^nd letter.
• T is the 20^th letter, Y is the 25^th letter.
• Comparing the first letters: Q (17) to T (20). The difference is \(20 - 17 = 3\).
• Comparing the second letters: V (22) to Y (25). The difference is \(25 - 22 = 3\).
• Pattern: The letters in the second cluster (TY) are 3 positions after the corresponding letters in the first cluster (QV).

Identifying the Odd Pair Out

By comparing the patterns identified in each pair:

• FK-IN follows a +3 shift for both letters.
• DI-GL follows a +3 shift for both letters.
• QV-TY follows a +3 shift for both letters.
• LP-NR follows a +2 shift for both letters.

The pairs FK-IN, DI-GL, and QV-TY all share the same pattern (a shift of +3 positions between the clusters). The pair LP-NR has a different pattern (a shift of +2 positions). Therefore, LP-NR is the pair that does not belong to the group.

Conclusion

The pair LP-NR does not follow the same alphabetical progression rule as the other pairs. Hence, it is the odd one out.
