Based on the position in the English alphabetical order, three of the following letterclusters are alike in some manner and one is different. Select the odd letter-cluster.
Finding the Odd Letter Cluster Based on Alphabetical Position
This question asks us to identify the letter cluster that is different from the others based on a pattern related to the position of letters in the English alphabet. We need to examine each cluster and determine the rule or pattern it follows.
Analyzing Letter Positions and Patterns
Let's assign a numerical value to each letter based on its position in the English alphabet (A=1, B=2, C=3, ..., Z=26). Then, we can look at the differences between the positions of consecutive letters within each cluster.
| Letter Cluster | Letter Positions | Differences Between Positions | Pattern |
|---|---|---|---|
| QUXZ | Q=17, U=21, X=24, Z=26 | U-Q = 21-17 = $\small{4}$ X-U = 24-21 = $\small{3}$ Z-X = 26-24 = $\small{2}$ |
$\small{+4, +3, +2}$ |
| GKOQ | G=7, K=11, O=15, Q=17 | K-G = 11-7 = $\small{4}$ O-K = 15-11 = $\small{4}$ Q-O = 17-15 = $\small{2}$ |
$\small{+4, +4, +2}$ |
| AEIK | A=1, E=5, I=9, K=11 | E-A = 5-1 = $\small{4}$ I-E = 9-5 = $\small{4}$ K-I = 11-9 = $\small{2}$ |
$\small{+4, +4, +2}$ |
| KOSU | K=11, O=15, S=19, U=21 | O-K = 15-11 = $\small{4}$ S-O = 19-15 = $\small{4}$ U-S = 21-19 = $\small{2}$ |
$\small{+4, +4, +2}$ |
Identifying the Different Pattern
After analyzing the patterns for each letter cluster:
- QUXZ follows the pattern: $\small{+4, +3, +2}$
- GKOQ follows the pattern: $\small{+4, +4, +2}$
- AEIK follows the pattern: $\small{+4, +4, +2}$
- KOSU follows the pattern: $\small{+4, +4, +2}$
We can see that three of the letter clusters (GKOQ, AEIK, KOSU) follow the same pattern where the differences between consecutive letter positions are +4, +4, and +2. The letter cluster QUXZ follows a different pattern of +4, +3, and +2.
Conclusion: Selecting the Odd Letter-Cluster
Based on the analysis of the alphabetical positions and the patterns of differences, the letter cluster that is different from the others is QUXZ.
Revision Table: Letter Cluster Patterns
| Letter Cluster | Pattern of Differences | Alike or Different |
|---|---|---|
| QUXZ | $\small{+4, +3, +2}$ | Different |
| GKOQ | $\small{+4, +4, +2}$ | Alike |
| AEIK | $\small{+4, +4, +2}$ | Alike |
| KOSU | $\small{+4, +4, +2}$ | Alike |
Additional Information: Letter Series Reasoning
Questions like this are common in reasoning sections of competitive exams. They test your ability to identify patterns in sequences of letters or numbers. The key is often to translate letters into numerical values (like alphabetical position) or look for relationships between consecutive letters (like skipping a certain number of letters).
- Alphabetical Position: Always remember or have access to the numerical position of each letter from A to Z.
- Pattern Recognition: Look for common arithmetic patterns (addition, subtraction, multiplication, division), sequential patterns (like prime numbers, squares, cubes), or alternating patterns.
- Consistency: A pattern must consistently apply to most elements in the set for it to be the rule that defines the group. The one that doesn't fit is the odd one out.
