What should come in place of the question mark (?) in the given series based on the English alphabetical order? PPR, SQN, VRJ,?
Show answer & explanation
Correct answer: A
Explanation
Series: PPR, SQN, VRJ, ?
examine the sequence letter by letter.
First letters:
P → S → V → ?
Positions in alphabet: P(16), S(19), V(22)
Pattern: +3 each time.
Next: V(22) + 3 = Y(25)
Second letters:
P → Q → R → ?
Positions: P(16), Q(17), R(18)
Pattern: +1 each time.
Next: R(18) + 1 = S(19)
Third letters:
R → N → J → ?
Positions: R(18), N(14), J(10)
Pattern: -4 each time.
Next: J(10) - 4 = F(6)
So, the missing term is YSF
Hence, the correct answer is option (1).
