What should come in place of the question mark (?) in the given series based on the English alphabetical order? MOK, LNJ, KMI, JLH, ?
HPJ
HJG
IKH
IKG
IKG
Observe the first, second, and third letters of each cluster independently; each follows a consistent reverse alphabetical movement of -1 position.
Observe the first, second, and third letters of each cluster independently; each follows a consistent reverse alphabetical movement of -1 position.
Analyze the pattern for the 1st, 2nd, and 3rd letters
Look at the sequence of the first letter: M(13), L(12), K(11), J(10). The next should be J-1 = I(9). Look at the second letter: O(15), N(14), M(13), L(12). The next should be L-1 = K(11). Look at the third letter: K(11), J(10), I(9), H(8). The next should be H-1 = G(7).
Assemble the final cluster
Combining the results: 1st letter I, 2nd letter K, 3rd letter G. The final cluster is IKG.
A: HPJ is wrong as it starts with H and ends with J, not I and G. B: HJG is wrong as the second letter is J instead of K. C: IKH is wrong as the last letter is H instead of G.
D is correct because each letter in the cluster shifts backwards by exactly one position in the English alphabet (M-1=L, O-1=N, K-1=J) consistently across the series.
When solving alphabetical series, write down the positions (1-26) immediately above the letters to identify arithmetic shifts (-1, +2, etc.) faster.
