Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?

GKO 11, IMQ 13, KOS 15, MQU 17, ?
Correct Answer
OSW 19
First Letter Pattern: Analyze the progression of the first letters of each cluster: G (+2 letters) -> I (+2) -> K (+2) -> M. Adding 2 to M leads to 'O'.Subseque......
💡 Analysis & Explanation
First Letter Pattern
Analyze the progression of the first letters of each cluster: G (+2 letters) -> I (+2) -> K (+2) -> M. Adding 2 to M leads to 'O'.
Subsequent Letters Pattern
The second letters follow an identical +2 jump logic: K -> M -> O -> Q. Moving +2 from Q gives 'S'. The third letters similarly leap by +2: O -> Q -> S -> U, logically leading to 'W'.
Numeric Progression
The number attached to the end of each cluster increases consistently by 2: 11, 13, 15, 17. The next natural number in this odd series is 19.
Conclusion
Merging these decoded elements correctly constructs the next cluster: OSW 19.
