In each of the following questions, four groups of letters are given, three of them are alike in a certain way while one is different. Choose the odd one.

Options

A. PRVX
B. MQTV
C. DHKM
D. BFIK

Answer

To solve the problem of identifying the odd group of letters from the given options, we will analyze each group step by step.

### Step 1: Analyze the First Group - PRVX
- **P (16)**:
- Next letter: R (17) → +1
- **R (17)**:
- Next letter: V (22) → +4
- **V (22)**:
- Next letter: X (24) → +2

The pattern observed is: +1, +4, +2.

### Step 2: Analyze the Second Group - MQTV
- **M (13)**:
- Next letter: Q (17) → +4
- **Q (17)**:
- Next letter: T (20) → +3
- **T (20)**:
- Next letter: V (22) → +2

The pattern observed is: +4, +3, +2.

### Step 3: Analyze the Third Group - DHKM
- **D (4)**:
- Next letter: H (8) → +4
- **H (8)**:
- Next letter: K (11) → +3
- **K (11)**:
- Next letter: M (13) → +2

The pattern observed is: +4, +3, +2.

### Step 4: Analyze the Fourth Group - BFIK
- **B (2)**:
- Next letter: F (6) → +4
- **F (6)**:
- Next letter: I (9) → +3
- **I (9)**:
- Next letter: K (11) → +2

The pattern observed is: +4, +3, +2.

### Conclusion
From the analysis:
- The first group (PRVX) has a different pattern: +1, +4, +2.
- The other three groups (MQTV, DHKM, BFIK) share the same pattern: +4, +3, +2.

Thus, the odd one out is **PRVX**.

### Final Answer
The odd one out is **PRVX**.
