To solve this question, we need to identify the pattern or rule that is being followed to obtain each term in the given sequence.
Let's analyze the given sequence: CMM, EOO, GQQ, ____, KUU
Looking at the sequence, we can observe that:
- The first letter of each term is increasing by 2 (C, E, G, ...)
- The second and third letters of each term remain the same (M, O, Q, ...)
- The last letter of each term is repeating the second letter (M, O, Q, ...)
Using this pattern, we can determine the missing term in the sequence.
The missing term should have the first letter increased by 2 from the previous term (GQQ). Therefore, the first letter of the missing term should be "I".
The second and third letters of the missing term should remain the same as the previous term (GQQ), which are "Q".
The last letter of the missing term should repeat the second letter, which is "Q".
Based on this analysis, the missing term in the sequence is "IQQ".
Therefore, the correct answer is option C) ISS.
