Which set of letters, when placed in order in the blanks of the given letter series, completes it?
_ K K D _ K D K _ D _ K
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → DKKK
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is DKK (3 letters), written four times:
Copy 1: DKK, so the blank here is D
Copy 2: DKK, so the blank here is K
Copy 3: DKK, so the blank here is K
Copy 4: DKK, so the blank here is K
The blanks, in order, are therefore D, K, K, K.
