Which pair of letters will come in place of the question mark (?) in the given series?
YF, WJ, UN, SR, QV, ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → OZ
In a series of letter pairs, each place in the pair follows its own rule, so the first and second letters are checked separately using their places in the alphabet.
First letters Y (25), W (23), U (21), S (19), Q (17): each is 2 places back, so next is \(17-2=15\), which is O
Second letters F (6), J (10), N (14), R (18), V (22): each is 4 places ahead, so next is \(22+4=26\), which is Z
So the missing pair is OZ.
