Answer

To solve the problem of finding the missing letter and number in the sequence D - 4, G - 7, I - 9, M - 13, we can follow these steps:

### Step 1: Identify the pattern
We need to observe the letters and their corresponding numbers. The letters are D, G, I, and M, and the numbers are 4, 7, 9, and 13.

### Step 2: Determine the position of each letter in the alphabet
- D is the 4th letter of the alphabet.
- G is the 7th letter of the alphabet.
- I is the 9th letter of the alphabet.
- M is the 13th letter of the alphabet.

### Step 3: Analyze the relationship between letters and numbers
We can see that the numbers correspond to the position of the letters in the alphabet:
- D (4) corresponds to 4.
- G (7) corresponds to 7.
- I (9) corresponds to 9.
- M (13) corresponds to 13.

### Step 4: Find the next letter in the sequence
The next letter after M (which is the 13th letter) is O (the 15th letter).

### Step 5: Write the answer
Thus, the missing letter and number is O - 15.

### Final Answer:
O - 15
