Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
AY, BX, ?, DV, EU, FT
Answer & explanation
Correct answer: option 2
Explanation:
AY, BX, ?, DV, EU, FT
The logic followed here is :
A → (+1) → B → (+1) → C → (+1) → D → (+1) → E → (+5) → F
Y → (-1) → X → (-1) → W → (-1) → V → (-1) → U → (+5) → T
So, the letter-cluster that replaces the (?) to complete the series is "CW"
