Explanation

To solve the problem of filling in the blanks in the series "abaa ___ aab ___ a ____a", we need to identify the pattern in the sequence.

### Step-by-Step Solution:

1. **Identify the Given Sequence**:
The sequence provided is: abaa ___ aab ___ a ____a.

2. **Analyze the Pattern**:
Let's break down the sequence:
- The first part is "abaa".
- The second part is "aab".
- The third part is "a".
- The fourth part is "a".

3. **Look for Repetitions**:
If we observe closely, we can see that:
- The first segment "abaa" has a pattern of 'a' and 'b' where 'a' appears twice followed by 'b' and then 'a' again.
- The second segment "aab" has 'a' appearing twice followed by 'b'.
- The third segment is just 'a'.
- The fourth segment is also 'a'.

4. **Fill in the Blanks**:
Based on the identified pattern:
- The first blank should be filled with 'a' to maintain the pattern of 'a' appearing twice.
- The second blank should be filled with 'b' to continue the sequence.
- The third blank should be filled with 'a' to follow the established pattern.

5. **Final Sequence**:
After filling in the blanks, the complete sequence becomes:
abaa **a** aab **b** a **a** a.

### Final Answer:
The completed sequence is: abaa **a** aab **b** a **a** a.
