Question : Directions: A series is given below with one term missing. Choose the correct alternative from the given ones that will complete the series.
GD, DI, AP, XY, ?
Option 1: UH
Option 2: IU
Option 3: ST
Option 4: UJ
Correct Answer: UJ
Solution :
Given:
GD, DI, AP, XY, ?
Subtract 3 from the positional value of the first letter and add consecutive odd numbers starting from 5 in increasing order to the positional value of the second number, to get the required missing term –
GD→G – 3 = D; D + 5 = I→DI
DI→D – 3 = A; I + 7 = P→AP
AP→A – 3 = X; P + 9 = Y→XY
XY→X – 3 = U; Y + 12 = J→UJ
So, the required missing term is UJ. Hence, the fourth option is correct.
