Which of the following terms will replace the question mark (?) in the given series?
ZXE ZWD ZVC ? ZTA
Answer & explanation
Correct answer: option 3

Explanation:
ZXE ZWD ZVC ? ZTA
The logic followed here is :
Z → (0) → Z → (0) → Z → (0) → Z → (0) → Z
X → (-1) → W → (-1) → V → (-1) → U → (-1) → T
E → (-1) → D → (-1) → C → (-1) → B → (-1) → A
So, the letter-cluster that replaces the (?) to complete the series is "ZUB"
