Select the odd letter group from the following alternatives based on the direction of the alphabetical sequence.

Introduction / Context:
This reasoning question checks your understanding of alphabetical sequences and the direction in which letters progress. Such problems often appear in verbal reasoning and series questions where you must quickly recognize patterns of increasing or decreasing letters in the English alphabet.

Given Data / Assumptions:

• The four letter groups given are: GHI, XYZ, VUT, and CDE.
• You are required to select the odd group based on the letter arrangement pattern.
• Assume standard English alphabet order with no wrapping beyond Z.

Concept / Approach:
The usual approach is to examine the order of letters in each group. You check whether each group follows increasing order (forward in the alphabet) or decreasing order (reverse in the alphabet). Once you know the direction of movement in each group, you can classify which one differs from the others.

Step-by-Step Solution:
Step 1: For GHI, the letters are G, H, and I. These are consecutive letters in forward order. Step 2: For XYZ, the letters X, Y, and Z are also consecutive and appear in forward alphabetical order. Step 3: For CDE, the letters C, D, and E again form a forward consecutive sequence. Step 4: For VUT, the letters are V, U, and T. Here, the sequence goes V to U to T, which is in reverse alphabetical order, not forward. Step 5: Therefore, three groups follow forward alphabetical order, while one group follows reverse order.

Verification / Alternative check:
You can also assign numerical positions to each letter. For example, G is 7, H is 8, I is 9 (increasing), X is 24, Y is 25, Z is 26 (increasing), C is 3, D is 4, E is 5 (increasing), but V is 22, U is 21, and T is 20 (decreasing). This numerical verification confirms that VUT is the only group in reverse order.

Why Other Options Are Wrong:

• GHI: All letters are consecutive and arranged in forward alphabetical order, so it matches the main pattern.
• XYZ: This group also forms a forward sequence of consecutive letters, so it is not odd.
• CDE: Again, these letters create a forward consecutive alphabetical sequence, so they follow the same rule.

Common Pitfalls:
Students sometimes focus only on whether the letters are consecutive and overlook the direction of the sequence. Because V, U, and T are consecutive, it may look regular at first glance. However, the forward versus reverse direction is the key feature that distinguishes VUT from the others.

Final Answer:
VUT
