Which letter cluster will come next to the series? ZC, WF, SI, NL, ?
Show answer & explanation
Correct answer: A
Explanation
Letter Cluster in the Series: ZC, WF, SI, NL, ?
First letters pattern:
Z (26th), W (23rd), S (19th), N (14th).
The positions decrease as follows:
26 → 23 (−3)
23 → 19 (−4)
19 → 14 (−5)
Following the pattern, the next step is:
14 − 6 = 8 → H.
Second letters pattern:
C (3rd), F (6th), I (9th), L (12th).
The positions increase as follows:
3 → 6 (+3)
6 → 9 (+3)
9 → 12 (+3)
Following the pattern, the next step is:
12 + 3 = 15 → O.
So, the next cluster is HO.
Hence, the correct answer is option (1).
