Correct Answer: KPO
Solution :
Given:
CXW, EVU, GTS, IRQ, ?
In the above-given series, add 2 to the place value of the first letter and subtract 2 from the place value of the second and third letters of the previous term to obtain the next term.
CXW→C + 2 = E; X – 2 = V; W – 2 = U
EVU→E + 2 = G; V – 2 = T; U – 2 = S
GTS→G + 2 = I; T – 2 = R; S – 2 = Q
IRQ→I + 2 = K; R – 2 = P; Q – 2 = O
So, KPO is the missing term of the series. Hence, the fourth option is correct.
