B. L - 14
C. U - 10
D. Z - 26

Answer

To solve the problem, we need to identify the pattern in the given pairs of letters and numbers. Let's break it down step by step.

### Step 1: Identify the position of each letter in the alphabet.
- F is the 6th letter.
- G is the 7th letter.
- J is the 10th letter.
- O is the 15th letter.

### Step 2: Identify the numbers associated with each letter.
- F is associated with 1.
- G is associated with 3.
- J is associated with 5.
- O is associated with 8.

### Step 3: Look for a pattern in the numbers.
The numbers associated with the letters seem to increase in a specific pattern:
- From F (1) to G (3): Increase of 2
- From G (3) to J (5): Increase of 2
- From J (5) to O (8): Increase of 3

### Step 4: Check the positions of the letters and the numbers.
- The position of F (6) + 1 = 7 (G)
- The position of G (7) + 3 = 10 (J)
- The position of J (10) + 5 = 15 (O)
- The position of O (15) + 8 = 23

### Step 5: Find the letter corresponding to the position 23.
The 23rd letter in the alphabet is W.

### Step 6: Determine the next number in the sequence.
Following the pattern, the next number after 8 should be 13 (since the increases were 2, 2, and 3, we can assume the next increase is 5).

### Conclusion:
The missing letter and number are W and 13, respectively.

### Final Answer:
W - 13
