Looking at the series: N5V, K7T, ?, E14P, B19N
Let me analyze each component separately.
For the first letters: N, K, ?, E, B
Position in alphabet:
- N = 14th letter
- K = 11th letter
- E = 5th letter
- B = 2nd letter
The pattern shows: 14, 11, ?, 5, 2
The difference is -3 each time.
14−3=11
11−3=8
8−3=5
5−3=2
The 8th letter of the alphabet is H.
For the numbers: 5, 7, ?, 14, 19
Looking at the differences between consecutive terms:
7−5=2
The differences form a pattern: 2, 3, 4, 5...
7+3=10
10+4=14
14+5=19
The missing number is 10.
For the last letters: V, T, ?, P, N
Position in alphabet:
- V = 22nd letter
- T = 20th letter
- P = 16th letter
- N = 14th letter
The pattern shows: 22, 20, ?, 16, 14
The difference is -2 each time.
22−2=20
20−2=18
18−2=16
16−2=14
The 18th letter of the alphabet is R.
The missing term is H10R.
Therefore, the answer is Option 3.
