Which two alpha-numeric sets will follow in the given series?
N-14, P-16, R-18, T-20, ?, ?

Options

A. X-24, P-16
B. L-12, O-15
C. V-22, Z-26
D. V-22, X-24

Answer

To solve the problem, we need to identify the pattern in the given series of alpha-numeric sets: N-14, P-16, R-18, T-20.

### Step-by-Step Solution:

1. **Identify the pattern in letters:**
- The letters in the series are: N, P, R, T.
- The positions of these letters in the alphabet are:
- N = 14
- P = 16
- R = 18
- T = 20
- We can see that the letters are increasing by 2 positions in the alphabet:
- N (14) → P (16) → R (18) → T (20)

2. **Determine the next letter:**
- Continuing the pattern, the next letter after T (20) will be:
- T (20) + 2 = V (22)

3. **Identify the pattern in numbers:**
- The numbers in the series are: 14, 16, 18, 20.
- The numbers are increasing by 2:
- 14 + 2 = 16
- 16 + 2 = 18
- 18 + 2 = 20

4. **Determine the next number:**
- Continuing the pattern, the next number after 20 will be:
- 20 + 2 = 22

5. **Identify the next set:**
- The next set after T-20 will be V-22.

6. **Continue the pattern:**
- Now we need to find the set that follows V-22.
- The next letter after V (22) will be:
- V (22) + 2 = X (24)
- The next number after 22 will be:
- 22 + 2 = 24

7. **Final answer:**
- The two alpha-numeric sets that follow in the series are V-22 and X-24.

### Conclusion:
The answer to the question is V-22 and X-24.
