Letter Cluster Pairs Reasoning: Identifying the Odd One Out
The task is to identify which letter-cluster pair is different from the others based on a hidden pattern related to alphabetical order. Three pairs share a common logic, while one deviates.
Analyzing Letter Cluster Patterns
We examine the relationship between the letters in each pair and how the first cluster relates to the second cluster. Assigning numerical values (A=1, B=2, ..., Z=26) helps reveal the pattern.
Common Pattern Identification
In the majority of the options, a consistent shift is observed:
- The first letter of the first cluster maps to the first letter of the second cluster with a specific backward shift.
- The second letter of the first cluster maps to the second letter of the second cluster with the same backward shift.
Evaluating Each Option
Option 1: SQ-PN
- S is the 19th letter, P is the 16th. Shift: $16 - 19 = -3$.
- Q is the 17th letter, N is the 14th. Shift: $14 - 17 = -3$.
- Pattern: Both letters shift back by 3 places. This fits the common pattern.
Option 2: ZX-WU
- Z is the 26th letter, W is the 23rd. Shift: $23 - 26 = -3$.
- X is the 24th letter, U is the 21st. Shift: $21 - 24 = -3$.
- Pattern: Both letters shift back by 3 places. This fits the common pattern.
Option 4: MK-JH
- M is the 13th letter, J is the 10th. Shift: $10 - 13 = -3$.
- K is the 11th letter, H is the 8th. Shift: $8 - 11 = -3$.
- Pattern: Both letters shift back by 3 places. This fits the common pattern.
Option 3: DB-ZA (The Odd One Out)
- D is the 4th letter, Z is the 26th. Shift: $26 - 4 = -6$ (or $+20$ if wrapping around the alphabet).
- B is the 2nd letter, A is the 1st. Shift: $1 - 2 = -1$.
- Pattern: The shifts (-6 and -1) are inconsistent with each other and do not match the -3 shift found in the other options.
| Option | 1st Letter Shift | 2nd Letter Shift | Common Pattern (-3)? |
|---|---|---|---|
| SQ-PN | $16 - 19 = -3$ | $14 - 17 = -3$ | Yes |
| ZX-WU | $23 - 26 = -3$ | $21 - 24 = -3$ | Yes |
| DB-ZA | $26 - 4 = -6$ | $1 - 2 = -1$ | No |
| MK-JH | $10 - 13 = -3$ | $8 - 11 = -3$ | Yes |
Conclusion: The Non-conforming Pair
The letter-cluster pair DB-ZA does not follow the established pattern of a consistent 3-position backward shift seen in SQ-PN, ZX-WU, and MK-JH. Therefore, DB-ZA is the odd one out.
