Choose the correct letter cluster to complete the series. ABCD, GHIJ, MNOP, ?
Show answer & explanation
Correct answer: A
Explanation
Given Series: ABCD, GHIJ, MNOP, ?
Identify the pattern
Check the alphabetical positions:
ABCD → positions 1, 2, 3, 4
GHIJ → positions 7, 8, 9, 10
MNOP → positions 13, 14, 15, 16
Each group contains four consecutive letters.
The starting letters increase by 6 position (A – G – M – S)
So, the next four letters are: S (19), T (20), U (21), V (22).
Therefore, the next cluster is STUV.
Hence, the correct answer is option (1).
