The sequence in the image is: 

\[
4, 4, 2, 5, 20, 4, 10, \ldots
\]

We need to determine the next number in the sequence.

### Step-by-step Analysis
Let's look for patterns:

1. **First Segment:** The first three numbers are \( 4, 4, 2 \). These don't show a clear arithmetic or geometric progression.

2. **Second Segment:** The numbers \( 5, 20 \) follow. If we observe, \( 20 = 5 \times 4 \). This suggests some form of multiplication might be at play here.

3. **Third Segment:** Then the sequence continues as \( 4, 10 \). We see that \( 10 = 4 \times 2.5 \).

### Finding the Pattern
The sequence seems to alternate between certain operations. One possibility is that it multiplies by a number that varies each time. Let's investigate further:

- \( 4 \rightarrow 4 \): No change.
- \( 4 \rightarrow 2 \): Divides by 2.
- \( 2 \rightarrow 5 \): Adds 3.
- \( 5 \rightarrow 20 \): Multiplies by 4.
- \( 20 \rightarrow 4 \): Divides by 5.
- \( 4 \rightarrow 10 \): Multiplies by 2.5.

### Determining the Next Number
If the pattern continues, we expect the sequence to alternate between operations. Following the pattern:

1. **After multiplying by 2.5 (10):** The next operation should be similar to earlier operations where we **divide**.

2. Dividing \( 10 \) by \( 2 \):
   \[
   10 \div 2 = 5
   \]

Thus, the next number in the sequence is **5**.

### Answer: 
The correct choice is:

\[
\boxed{5}
\]
