Which set of letters, when placed in order in the blanks of the given letter series, completes it?
P _ Q _ R P P _ Q Q _ P
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → RQRR
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is PRQQRP (6 letters), written twice:
Group 1: PRQQRP, so the blanks here are R, Q
Group 2: PRQQRP, so the blanks here are R, R
The blanks, in order, are therefore R, Q, R, R.
