Analyzing the Letter Series: Finding the Odd One Out

In this type of question, we are given a set of letter pairs or groups and need to identify the one that does not follow the same rule or pattern as the others. To do this, we usually look at the alphabetical positions of the letters or the relationship between them, such as the difference in position or the number of letters skipped.

Analyzing Each Option

Let's examine the relationship between the letters in each given pair:

• VT: Consider the alphabetical order. From T to V, we have T → U → V. There is one letter (U) skipped between T and V. Using alphabetical positions (A=1, B=2, ...), T is the 20th letter and V is the 22nd letter. The difference in position is \(22 - 20 = +2\).
• PR: Consider the alphabetical order. From P to R, we have P → Q → R. There is one letter (Q) skipped between P and R. Using alphabetical positions, P is the 16th letter and R is the 18th letter. The difference in position is \(18 - 16 = +2\).
• FG: Consider the alphabetical order. From F to G, we have F → G. There are zero letters skipped; they are consecutive letters. Using alphabetical positions, F is the 6th letter and G is the 7th letter. The difference in position is \(7 - 6 = +1\).
• MQ: Consider the alphabetical order. From M to Q, we have M → N → O → P → Q. There are three letters (N, O, P) skipped between M and Q. Using alphabetical positions, M is the 13th letter and Q is the 17th letter. The difference in position is \(17 - 13 = +4\).

Identifying the Common Pattern

Let's compare the patterns found:

• VT: Skips 1 letter (T to V), position difference +2
• PR: Skips 1 letter (P to R), position difference +2
• FG: Skips 0 letters (F to G), position difference +1
• MQ: Skips 3 letters (M to Q), position difference +4

We can see that the pairs VT and PR share a common pattern: there is exactly one letter skipped between the two letters (moving forward alphabetically), or the second letter is two positions after the first letter.

The pair FG consists of consecutive letters, meaning zero letters are skipped, and the position difference is +1.

The pair MQ skips three letters, and the position difference is +4.

Conclusion

The pairs VT and PR follow the pattern of skipping one letter (or a position difference of +2). The pair FG does not follow this pattern as it skips zero letters (consecutive, position difference of +1). The pair MQ also does not follow the common pattern (skips three letters, position difference of +4).

Among the given options, FG is the only pair where the letters are consecutive. Therefore, FG is the odd one out.
