Answer

To find the missing letters in the sequence ABZ, BCY, CDX, DEW, we will analyze the pattern in each position of the letters.

1. **Identify the first letters:**
- The first letters are A, B, C, D, and we need to find the next letter.
- The pattern is:
- A → B (A + 1)
- B → C (B + 1)
- C → D (C + 1)
- D → E (D + 1)
- Therefore, the next letter in the sequence is **E**.

2. **Identify the second letters:**
- The second letters are B, C, D, E, and we need to find the next letter.
- The pattern is:
- B → C (B + 1)
- C → D (C + 1)
- D → E (D + 1)
- E → F (E + 1)
- Therefore, the next letter in the sequence is **F**.

3. **Identify the third letters:**
- The third letters are Z, Y, X, W, and we need to find the next letter.
- The pattern is:
- Z → Y (Z - 1)
- Y → X (Y - 1)
- X → W (X - 1)
- W → V (W - 1)
- Therefore, the next letter in the sequence is **V**.

Putting it all together, the missing letters are E, F, and V.

**Final Answer:** The missing letters are **EFV**.
