To solve the sequence a__ab__baa__bb___, we need to identify a pattern that fits the blanks. Let's analyze the sequence step by step.

### Step 1: Identify the given sequence
The sequence provided is:
- a__ab__baa__bb___

### Step 2: Analyze the existing letters
We can break down the sequence into parts:
1. a
2. ab
3. baa
4. bb

### Step 3: Look for patterns
Let's examine the letters:
- The first part starts with 'a'.
- The second part has 'ab'.
- The third part has 'baa'.
- The fourth part has 'bb'.

### Step 4: Fill in the blanks
We need to find letters that can fill the blanks in a way that maintains a pattern.

1. The first blank after 'a' could be 'a' (making it 'aa').
2. The second blank after 'ab' could be 'a' (making it 'aba').
3. The third blank after 'baa' could be 'b' (making it 'baab').

- aa
- aba
- baab
- bba

This sequence does not seem to follow a clear pattern.

### Step 6: Try another approach
