Question : Directions: A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
NMR, QFZ, TYH, WRP, ?
Option 1: ZRS
Option 2: ZKX
Option 3: ZXY
Option 4: ZAM
Correct Answer: ZKX
Solution :
Given:
NMR, QFZ, TYH, WRP, ?
Add 3 and 8 to the place value of the first and third letters respectively, and subtract 7 from the place value of the second letter of the previous term to obtain the next term in the series –
NMR→N + 3 = Q; M – 7 = F; R + 8 = Z→QFZ
QFZ→Q + 3 = T; F – 7 = Y; Z + 8 = H→TYH
TYH→T + 3 = W; Y – 7 = R; H + 8 = P→WRP
WRP→W + 3 = Z; R – 7 = K; P + 8 = X→ZKX
So, ZKX is the missing term of the series. Hence, the second option is correct.
