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. RTW
B. QSU
C. FHJ
D. IKM

Answer

To solve the problem of identifying the odd group of letters from the given options, we will analyze each group based on the pattern of letter progression.

**Step 1: Analyze the first option (R, T, W)**
- Start with R:
- R to T: Move 2 steps forward (R → S → T)
- T to W: Move 3 steps forward (T → U → V → W)
- The pattern here is +2, +3.

**Step 2: Analyze the second option (Q, S, U)**
- Start with Q:
- Q to S: Move 2 steps forward (Q → R → S)
- S to U: Move 2 steps forward (S → T → U)
- The pattern here is +2, +2.

**Step 3: Analyze the third option (F, H, J)**
- Start with F:
- F to H: Move 2 steps forward (F → G → H)
- H to J: Move 2 steps forward (H → I → J)
- The pattern here is +2, +2.

**Step 4: Analyze the fourth option (I, K, M)**
- Start with I:
- I to K: Move 2 steps forward (I → J → K)
- K to M: Move 2 steps forward (K → L → M)
- The pattern here is +2, +2.

**Step 5: Compare the patterns**
- From the analysis:
- Option 1 (R, T, W): +2, +3
- Option 2 (Q, S, U): +2, +2
- Option 3 (F, H, J): +2, +2
- Option 4 (I, K, M): +2, +2

**Conclusion:**
The odd one out is **Option 1 (R, T, W)** because it follows a different pattern (+2, +3) compared to the others which follow the same pattern (+2, +2).

**Final Answer:** Option 1 (R, T, W)
