Finding the Odd Group of Letters in Alphabet Series

This question asks us to identify the group of letters that is different from the others based on a hidden pattern. To solve this type of reasoning question, we usually look at the position of the letters in the English alphabet.

Let's examine each group of letters and their positions in the alphabet:

From the analysis above, we can see the pattern:

• In groups EFG, PQR, and VWX, the letters are consecutive in the alphabet. The difference in alphabetical position between successive letters is \(\text{+1}\).
• In the group HJL, the letters are not consecutive. The difference in alphabetical position between successive letters is \(\text{+2}\).

The group HJL follows a different pattern compared to the other three groups. Therefore, HJL is the odd group of letters.

Additional Information: Letter Series Reasoning

Letter series questions are common in reasoning tests. They test your ability to identify patterns in sequences of letters. These patterns can be based on various rules:

• Alphabetical Position: Analyzing the position of letters (A=1, B=2, ..., Z=26).
• Difference in Position: Looking at the numerical difference between the positions of consecutive letters. This difference can be constant, increasing, decreasing, or follow a specific sequence.
• Vowels/Consonants: Patterns might involve the arrangement of vowels and consonants.
• Skipping Letters: Letters might be skipped in a consistent manner (e.g., skipping one letter, two letters, etc.).
• Reverse Alphabetical Order: The series might run backward through the alphabet.

To solve letter series problems, always start by writing down the alphabetical positions of the letters and calculating the differences between them. This often reveals the underlying pattern.
