Correct Answer: FMU
Solution :
Given:
XEM, ZGO, BIQ, DKS, ?
Add 2 to the place value of each letter of the previous letter cluster to obtain the next letter cluster in the series –
XEM→X + 2 = Z; E + 2 = G; M + 2 = O→ZGO
ZGO→Z + 2 = B; G + 2 = I; O + 2 = Q→BIQ
BIQ→B + 2 = D; I + 2 = K; Q + 2 = S→DKS
DKS→D + 2 = F; K + 2 = M; S + 2 = U→FMU
So, FMU is the missing letter cluster in the series. Hence, the first option is correct.
