Find the next term of the following letter series :
DHL, PTX, BFJ, .....

Question

Accepted Answer

To determine the next term in the letter series DHL, PTX, BFJ, we need to analyze the pattern in the sequence.

1. **Pattern Analysis:**
   - **DHL:**
     - D is the 4th letter of the alphabet.
     - H is the 8th letter of the alphabet.
     - L is the 12th letter of the alphabet.
     - The pattern here is an increment of 4 between each letter (D+4=H, H+4=L).

- **PTX:**
     - P is the 16th letter of the alphabet.
     - T is the 20th letter of the alphabet.
     - X is the 24th letter of the alphabet.
     - The pattern here is also an increment of 4 between each letter (P+4=T, T+4=X).

- **BFJ:**
     - B is the 2nd letter of the alphabet.
     - F is the 6th letter of the alphabet.
     - J is the 10th letter of the alphabet.
     - The pattern here is again an increment of 4 between each letter (B+4=F, F+4=J).

2. **Finding the Next Term:**
   - Following the same pattern of incrementing by 4:
     - Start with N (14th letter of the alphabet).
     - Add 4 to get R (18th letter of the alphabet).
     - Add 4 to get V (22nd letter of the alphabet).
   - Therefore, the next term is NRV.

3. **Explanation of Incorrect Options:**
   - **Option 1: CGK**
     - C is the 3rd letter, G is the 7th, and K is the 11th. The increments here are 4, but starting from C does not follow the sequence pattern.
   
   - **Option 2: KOS**
     - K is the 11th letter, O is the 15th, and S is the 19th. The increments are 4, but starting from K does not align with the sequence pattern.
   
   - **Option 4: OVZ**
     - O is the 15th letter, V is the 22nd, and Z is the 26th. The increments are not consistent with the pattern observed in the series.

Thus, based on the consistent pattern of incrementing by 4, Option 3 (NRV) is the correct answer.
