Correct Answer: YTA
Solution :
Given:
GBW, EZX, CXY, AVZ, ?
Here, subtract 2 from the place value of the first and the second letters and add 1 to the place value of the third letter to the previous term to get the next term –
GBW→G – 2 = E; B – 2 = Z; W + 1 = X→EZX
EZX→E – 2 = C; Z – 2 = X; X + 1 = Y→CXY
CXY→C – 2 = A; X – 2 = V; Y + 1 = Z→AVZ
AVZ→A – 2 = Y; V – 2 = T; Z + 1 = A→YTA
So, YTA is the missing term in the series. Hence, the second option is correct.
