Select the alphanumeric term that can replace the question mark (?) in the following series. Z63C, X31F, V15I, T7L, R3O, ?
The question requires finding the next term in the given alphanumeric series: Z63C, X31F, V15I, T7L, R3O, ?. We need to identify the pattern for the first letter, the number, and the second letter separately.
The sequence of the first letters is Z, X, V, T, R. Let's examine their positions in the alphabet:
The pattern involves subtracting 2 from the position of the preceding letter (26 - 2 = 24, 24 - 2 = 22, etc.). Following this pattern, the next letter's position will be $18 - 2 = 16$. The 16th letter of the alphabet is P.
The sequence of numbers is 63, 31, 15, 7, 3. Let's look at the difference between consecutive terms:
The differences (32, 16, 8, 4) are halving each time. The next difference should be $4 / 2 = 2$. Therefore, the next number in the sequence is $3 - 2 = 1$.
The sequence of the second letters is C, F, I, L, O. Let's examine their positions in the alphabet:
The pattern involves adding 3 to the position of the preceding letter (3 + 3 = 6, 6 + 3 = 9, etc.). Following this pattern, the next letter's position will be $15 + 3 = 18$. The 18th letter of the alphabet is R.
Combining the results from the patterns identified:
The complete alphanumeric term that replaces the question mark (?) is P1R.
A series is given with one term missing. Select the correct alternative from the given options that will complete the series.
