Explanation

To solve the sequence aa ___ b ____abb____bb, we need to find the appropriate letters to fill in the blanks to create a consistent pattern.

### Step-by-Step Solution:

1. **Identify the given sequence**:
The sequence we have is: aa ___ b ____ abb ____ bb.

2. **Analyze the existing letters**:
We see that there are two 'a's at the beginning, followed by a 'b', then 'abb', and finally 'bb'.

3. **Look for patterns**:
We can observe that the sequence starts with 'aa', followed by 'b', and then 'abb' which suggests that 'a' might be repeated in the blanks.

4. **Fill in the first blank**:
Let's try filling the first blank with 'a'. So we have: aa a b ____ abb ____ bb.

5. **Fill in the second blank**:
Now, let's fill the second blank with 'b'. So we have: aa a b b abb ____ bb.

6. **Fill in the third blank**:
Next, we need to fill the third blank. Since we have 'abb', we can fill this with 'a' to maintain the pattern. So we have: aa a b b abb a bb.

7. **Final sequence**:
The completed sequence is: aa a b b abb a bb.

8. **Check for consistency**:
The sequence now reads: aa a b b abb a bb, which shows a consistent pattern of 'a's and 'b's.

### Final Answer:
The completed sequence is: aa a b b abb a bb.
