Question

Complete the series by filling the blank with the suitable alternative.
CMM, EOO, GQQ, _ _ , KUU

• A. GRR
• B. HRR
• C. ISS
• D. IRS
• E. HSS

Hint:

Break the letter series into individual components (first, second, third letter) to find the pattern for each.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Analyze each letter position (1st, 2nd, and 3rd) separately to find the alphabet progression.
Step 2: Identifying the Vector of Change:
- 1st Letter: C, E, G, \_\_, K. (C+2=E, E+2=G, G+2=I, I+2=K). The missing 1st letter is I. - 2nd & 3rd Letters: MM, OO, QQ, \_\_, UU. (M+2=O, O+2=Q, Q+2=S, S+2=U). The missing 2nd and 3rd letters are SS.
Step 3: Calculation:
Combining these results: I + SS = ISS.
Step 4: Final Answer:
The missing group in the series is ISS. Thus, the correct option is (c).
