Which set of letters, when placed in the blanks of the given letter series in order, will complete it?
e _ h d _ e g h _ f e _ h d f
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → gfdg
In a letter series with blanks, look for a block of letters that repeats; the blanks are then the letters the block needs at those places. The 15 places split into three blocks of five, each e g h d f; the second block shows g and f, the third shows h, d and f.
Block 1: e _ h d _ needs g, f
Block 2: e g h _ f needs d
Block 3: e _ h d f needs g
The series is eghdf eghdf eghdf, and the blanks in order are gfdg.
