A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
MQRT, QUVX, UYZB, YCDF, ?

Correct option is B

Given series and find the pattern: MQRT, QUVX, UYZB, YCDF, ?
The logic given is +4 for each letter in the sequence. Let's apply this to each term:
MQRT → QUVX
M + 4 = Q
Q + 4 = U
R + 4 = V
T + 4 = X
QUVX → UYZB
Q + 4 = U
U + 4 = Y
V + 4 = Z
X + 4 = B
UYZB → YCDF
U + 4 = Y
Y + 4 = C
Z + 4 = D
B + 4 = F
YCDF → ?
Y + 4 = C
C + 4 = G
D + 4 = H
F + 4 = J
So, the next term in the series is CGHJ.
Therefore, the correct answer is: (b) CGHJ
