Answer

To find the missing letter in the series Y, W, U, S, ?, O, we will analyze the pattern in the sequence by looking at the positions of the letters in the alphabet.

1. **Identify the positions of the letters:**
- Y is the 25th letter of the alphabet.
- W is the 23rd letter of the alphabet.
- U is the 21st letter of the alphabet.
- S is the 19th letter of the alphabet.
- O is the 15th letter of the alphabet.

2. **Write down the positions:**
- Y = 25
- W = 23
- U = 21
- S = 19
- ? = ?
- O = 15

3. **Calculate the differences between the positions:**
- The difference between Y (25) and W (23) is 2.
- The difference between W (23) and U (21) is 2.
- The difference between U (21) and S (19) is 2.
- The difference between S (19) and O (15) is 4.

4. **Determine the missing letter's position:**
- The pattern shows that we are decreasing by 2 for the first four letters.
- Continuing this pattern, the next letter after S (19) should be 19 - 2 = 17.

5. **Identify the letter corresponding to position 17:**
- The 17th letter of the alphabet is Q.

Thus, the missing letter in the series is **Q**.

Final Answer: (d) Q
