What should come in place of '?' in the given series based on the English alphabetical order? YKQ QCI IUA AMS ?
SEK
Look at each of the three letter positions separately across the terms YKQ, QCI, IUA, AMS.
First letters: Y, Q, I, A. Each drops by 8 places (with wrap-around): Y(25)−8=Q(17), Q(17)−8=I(9), I(9)−8=A(1), A(1)−8=25−8+26 wrap → S(19).
Second letters: K, C, U, M. Each also moves by 8 with wrap: K(11)−8=C(3), C(3)−8 wrap → U(21), U(21)−8=M(13), M(13)−8=E(5).
Third letters: Q, I, A, S. Q(17)−8=I(9), I(9)−8=A(1), A(1)−8 wrap → S(19), S(19)−8=K(11).
So the next term is formed by S, E, K.
Hence, the missing term is SEK.
