Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
YZ, BCD, FGHI, ?, QRSTUV
Answer & explanation
Correct answer: option 3
Explanation:
YZ, BCD, FGHI, ?, QRSTUV
The logic followed here is :
Y → (+3) → B → (+4) → F → (+5) → K → (+6) → Q
Z → (+3) → C → (+4) → G → (+5) → L → (+6) → R
D → (+4) → H → (+5) → M → (+6) → S
I → (+5) → N → (+6) → T
(J)→ (+5) → O → (+6) → U
(P) → (+6) → V
So, the letter-cluster that replaces the (?) to complete the series is "KLMNO"
