Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
QTW 13, MPS 19, ILO 25, EHK 31, ADG 37, ?
-
A.
WZC 47
-
B.
ZZC 43
-
C.
WGC 43
-
D.
WZC 43
Correct Answer:
D. WZC 43
Explanation:
The correct answer is Option D: WZC 43.
The series follows a specific pattern for the letters and numbers:1. Letters:
Each cluster shifts backward in the alphabet by 4 positions for each corresponding letter.
First letter: Q (-4) -\> M (-4) -\> I (-4) -\> E (-4) -\> A (-4) -\> W
Second letter: T (-4) -\> P (-4) -\> L (-4) -\> H (-4) -\> D (-4) -\> Z
Third letter: W (-4) -\> S (-4) -\> O (-4) -\> K (-4) -\> G (-4) -\> C
Following this pattern, the next letter cluster is WZC.
2. Numbers:
The numerical sequence increases by 6 in each step: 13, 19, 25, 31, 37. Adding 6 to 37 results in 43.Combining these two patterns, the logical next step in the series is WZC 43.
