Which combination of letters completes the given series: NRJ, PNP, RJV?

Options

A. BFT
B. TFB
C. TBF
D. BTF

Explanation

To solve the problem of finding the combination of letters that completes the series NRJ, PNP, RJV, we will analyze the pattern in the series step by step.

### Step 1: Identify the given series
The given series is:
1. NRJ
2. PNP
3. RJV

### Step 2: Break down each group of letters
We will analyze the letters in each group separately:
- First group: N, R, J
- Second group: P, N, P
- Third group: R, J, V

### Step 3: Analyze the first letters of each group
- N (14th letter) to P (16th letter): +2
- P (16th letter) to R (18th letter): +2

### Step 4: Analyze the second letters of each group
- R (18th letter) to N (14th letter): -4
- N (14th letter) to J (10th letter): -4

### Step 5: Analyze the third letters of each group
- J (10th letter) to P (16th letter): +6
- P (16th letter) to V (22nd letter): +6

### Step 6: Predict the next group of letters
Now we will apply the same pattern to find the next group of letters.

1. **First letter**:
- Last first letter is R (18th letter).
- Following the pattern (+2): R (18) + 2 = T (20).

2. **Second letter**:
- Last second letter is J (10th letter).
- Following the pattern (-4): J (10) - 4 = F (6).

3. **Third letter**:
- Last third letter is V (22nd letter).
- Following the pattern (+6): V (22) + 6 = B (2).

### Step 7: Combine the letters
The next group of letters is TFB.

### Conclusion
The combination of letters that completes the given series is **TFB**.
