Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
YZCD, WXEF, UVGH, STIJ,?
Answer & explanation
Correct answer: option 4
Explanation:
YZCD, WXEF, UVGH, STIJ,?
The logic followed here is :
Y → (-2) → W → (-2) → U → (-2) → S → (-2) → Q
Z → (-2) → X → (-2) → V → (-2) → T → (-2) → R
C → (+2) → E → (+2) → G → (+2) → I → (+2) → K
D → (+2) → F → (+2) → H → (+2) → J → (+2) → L
So, the letter-cluster that replaces the (?) to complete the series is "QRKL"
