Find the next one in the following series.
ZAY, XBW, VCU, TDS, ___________
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → REQ
In a letter series, each position of the term follows its own rule, so the first, second and third letters are followed separately.
First letters Z, X, V, T: each is 2 places back in the alphabet, so the next is R
Second letters A, B, C, D: each is 1 place ahead, so the next is E
Third letters Y, W, U, S: each is 2 places back, so the next is Q
The next term is R, E, Q, that is, REQ.
