Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the one that is different.
Letter Cluster Reasoning: Identifying the Different Group
The question presents four groups of letters (letter-clusters) and asks us to identify the one group that does not follow the same pattern as the others. We need to find the odd one out.
Analyzing Letter Patterns
To solve this, we will examine the relationship between consecutive letters in each cluster by looking at their positions in the English alphabet.
Alphabet Positions:
- A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9, J=10, K=11, L=12, M=13, N=14, O=15, P=16, Q=17, R=18, S=19, T=20, U=21, V=22, W=23, X=24, Y=25, Z=26
Cluster Analysis
1. TXBF
Let's find the alphabetical positions:
- T = 20
- X = 24
- B = 2
- F = 6
Now, let's look at the difference between consecutive letters:
- T (20) to X (24): $24 - 20 = +4$
- X (24) to B (2): Since we wrap around the alphabet (Z is followed by A), we calculate this as $(24 + 4) \mod 26 = 28 \mod 26 = 2$. The difference is +4.
- B (2) to F (6): $6 - 2 = +4$
The pattern for TXBF is +4, +4, +4.
2. MQUY
Alphabetical positions:
- M = 13
- Q = 17
- U = 21
- Y = 25
Differences between consecutive letters:
- M (13) to Q (17): $17 - 13 = +4$
- Q (17) to U (21): $21 - 17 = +4$
- U (21) to Y (25): $25 - 21 = +4$
The pattern for MQUY is +4, +4, +4.
3. CGKO
Alphabetical positions:
- C = 3
- G = 7
- K = 11
- O = 15
Differences between consecutive letters:
- C (3) to G (7): $7 - 3 = +4$
- G (7) to K (11): $11 - 7 = +4$
- K (11) to O (15): $15 - 11 = +4$
The pattern for CGKO is +4, +4, +4.
4. VYCG
Alphabetical positions:
- V = 22
- Y = 25
- C = 3
- G = 7
Differences between consecutive letters:
- V (22) to Y (25): $25 - 22 = +3$
- Y (25) to C (3): $(25 + 4) \mod 26 = 29 \mod 26 = 3$. The difference is +4.
- C (3) to G (7): $7 - 3 = +4$
The pattern for VYCG is +3, +4, +4.
Conclusion
Comparing the patterns:
- TXBF follows the pattern: +4, +4, +4
- MQUY follows the pattern: +4, +4, +4
- CGKO follows the pattern: +4, +4, +4
- VYCG follows the pattern: +3, +4, +4
Three of the letter clusters (TXBF, MQUY, CGKO) share a common pattern where each letter is 4 positions after the previous one in the alphabet (with wrap-around). The cluster VYCG differs because the first step is +3, not +4.
Therefore, VYCG is the letter cluster that is different.
| Cluster | Positions | Differences | Pattern |
|---|---|---|---|
| TXBF | 20, 24, 2, 6 | +4, +4, +4 | Consistent +4 |
| MQUY | 13, 17, 21, 25 | +4, +4, +4 | Consistent +4 |
| CGKO | 3, 7, 11, 15 | +4, +4, +4 | Consistent +4 |
| VYCG | 22, 25, 3, 7 | +3, +4, +4 | Inconsistent (+3 first) |
