Select the alphanumeric term that can replace the question mark (?) in the following series. E972D, H324E, K108G, N36J, Q12N, ?
To solve this series question, let us analyze the pattern in the alphanumeric terms given:
The series is: E972D, H324E, K108G, N36J, Q12N, ?
- Alphabet Logic:
- The first letter of each term follows a pattern: E, H, K, N, Q.
- We notice that each letter is incremented by 3 in the alphabetical sequence.
- E + 3 = H, H + 3 = K, K + 3 = N, N + 3 = Q.
- Following this pattern, Q + 3 leads to the letter T.
- Numerical Logic:
- The numbers are: 972, 324, 108, 36, 12.
- The pattern here seems to be dividing the previous number by 3:
- 972 / 3 = 324, 324 / 3 = 108, 108 / 3 = 36, 36 / 3 = 12.
- Following the logic, 12 / 3 = 4.
- Last Letter Logic:
- The last letters are D, E, G, J, N.
- By converting these letters to their alphabetic position (A=1, B=2, ..., Z=26): D=4, E=5, G=7, J=10, N=14.
- The differences between consecutive alphabetic positions show a pattern:
- E - D = 1, G - E = 2, J - G = 3, N - J = 4.
- Following this pattern, the next position should be N + 5 = S (since the differences are increasing by 1).
Thus, by combining all the elements of the found patterns, the term that fits in the series is T4S.
Therefore, the correct option is T4S.
