Which set of letters, when placed in order in the blanks of the given letter series, completes it?
P _ R _ _ _ R R P Q _ R
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → QRPQR
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is PQRR (4 letters), written again and again:
Group 1: PQRR, so the blanks here are Q, R
Group 2: PQRR, so the blanks here are P, Q
Group 3: PQRR, so the blank here is R
The blanks, in order, are therefore Q, R, P, Q, R.
