Given:
LB, NZ, PX, RV, ?
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 letter.
LB→L + 2 = N; B – 2 = Z
NZ→N + 2 = P; Z – 2 = X
PX→P + 2 = R; X – 2 = V
RV→R + 2 = T; V – 2 = T
So, the next term of the series is TT. Hence, the fourth option is correct.
