Question : Directions: Which letter cluster will replace the question mark (?) in the following series?
SQO, LJH, ECA, ?
Option 1: XUS
Option 2: XVT
Option 3: YWV
Option 4: YWU
Correct Answer: XVT
Solution :
Given:
SQO, LJH, ECA, ?
Subtract 7 from each letter of the previous term to obtain the next term in the series –
SQO
→
S – 7 = L; Q – 7 = J; O – 7 = H
LJH
→
L – 7 = E; J – 7 = C; H – 7 = A
ECA
→
E – 7 = X; C – 7 = V; A – 7 = T
So, XVT is the missing term in the series. Hence, the second option is correct.
