Question : Directions: Select the option that will fill in the blank and complete the given series.
DXB, GSI, JNP, MIW, _____
Option 1: OED
Option 2: ODE
Option 3: PDD
Option 4: PDE
Correct Answer: PDD
Solution :
Given:
DXB, GSI, JNP, MIW, _____
Add 3 and 7 in the first and the third letter respectively and subtract 5 from the second letter, to get the required missing term –
DXB→D + 3 = G; X – 5 = S; B + 7 = I→GSI
GSI→G + 3 = J; S – 5 = N; I + 7 = P→JNP
JNP→J + 3 = M; N – 5 = I; P + 7 = W→MIW
MIW→M + 3 = P; I – 5 = D; W + 7 = D→PDD
Therefore, the required missing term in the series is PDD. Hence, the third option is correct.
