Question

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
PGE 18, TEI 26, XCM 34, BAQ 42, ?

A.

FCV 52

B.

FCU 52

C.

GYV 50

D.

FYU 50

Correct option is D

Given: PGE 18, TEI 26, XCM 34, BAQ 42, ?
Logic: 1st letter + 4, 2nd letter - 2, 3rd letter + 4 and number + 8 place.
For, 1st letter
P + 4 = T, T + 4 = X, X + 4 = B, B + 4 = F
For, 2nd letter
G - 2 = E, E - 2 = C, C - 2 = A, A - 2 = Y
For, 3rd letter
E + 4 = I, I + 4 = M, M + 4 = Q, Q + 4 = U
For, number
18 + 8 = 26, 26 + 8 = 34, 34 + 8 = 42, 42 + 8 = 50
So, the missing term is FYU 50.
Thus, correct option is (d).
