Answer

To find the missing letter in the series A, B, D, G, we can analyze the pattern of the letters and their positions in the alphabet.

1. **Identify the positions of the letters in the alphabet:**
- A is the 1st letter.
- B is the 2nd letter.
- D is the 4th letter.
- G is the 7th letter.

2. **Calculate the differences between the positions:**
- From A (1) to B (2): 2 - 1 = 1 (add 1)
- From B (2) to D (4): 4 - 2 = 2 (add 2)
- From D (4) to G (7): 7 - 4 = 3 (add 3)

3. **Identify the pattern in the differences:**
- The differences are increasing by 1 each time: +1, +2, +3.

4. **Determine the next difference:**
- Following the pattern, the next difference should be +4.

5. **Apply the next difference to G:**
- G is the 7th letter, so we add 4: 7 + 4 = 11.

6. **Find the letter corresponding to the 11th position:**
- The 11th letter of the alphabet is K.

Thus, the missing letter in the series A, B, D, G, … is K.

**Final Answer: K**
