Question

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
PET 23, TJN 32, XOH 41, BTB 50, ?

A.

GZV 57

B.

FYV 59

C.

GYU 59

D.

FZV 57

Correct option is B

Given: PET 23, TJN 32, XOH 41, BTB 50, ?
Logic: 1st letter + 4, 2nd letter + 5, 3rd letter - 6 and number + 9 place.
For, 1st letter
P + 4 = T, T + 4 = X, X + 4 = B, B + 4 = F
For, 2nd letter
E + 5 = J, J + 5 = O, O + 5 = T, T + 5 = Y
For, 3rd letter
T - 6 = N, N - 6 = H, H - 6 = B, B - 6 = V
For, number
23 + 9 = 32, 32 + 9 = 41, 41 + 9 = 50, 50 + 9 = 59
So, the missing term is FYV 59.
Thus, correct option is (b).
