What should come next in the following series?
A B C D E F Z Y X W V U A B C D E Z Y X W V U A B C D Z Y X W V
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → U
The series is made of runs of letters. A forward run starting at A, one letter shorter each time, is followed every time by the backward run Z Y X W V U:
A B C D E F | Z Y X W V U
A B C D E | Z Y X W V U
A B C D | Z Y X W V ?
The last backward run has reached V, so the next letter is U.
