Which group of letters will come in place of the question mark (?) in the given series?
QAR, RAS, SAT, TAU, ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → UAV
In a series of letter groups, each place in the group follows its own rule, so the first, middle and last letters are checked separately.
First letters Q, R, S, T: each is the next letter of the alphabet, so next is U
Middle letter: it is A every time, so it stays A
Last letters R, S, T, U: each is the next letter of the alphabet, so next is V
So the next group is UAV.
