The problem involves finding the operation that goes in the blank spaces. The pattern appears to be involving a sequence of operations.

Let's break it down:

1. **First Step:** \(13 \_ (-3)\)
   - Possible operations: addition (+), subtraction (-), multiplication (\(\times\)), division (\(\div\)).

2. **Second Step:** (?) 5 
   - Continue with the operation applied from the first step.

3. **Third Step:** 2 
   - Again, continue with the operation applied from the previous steps.

Now, let's try each operation:

- **Addition:**
  \[
  13 + (-3) = 10
  \]
  \[
  10 + 5 = 15
  \]
  \[
  15 + 2 = 17
  \]
  This yields \(17\).

- **Subtraction:**
  \[
  13 - (-3) = 16
  \]
  \[
  16 - 5 = 11
  \]
  \[
  11 - 2 = 9
  \]
  This yields \(9\).

- **Multiplication:**
  \[
  13 \times (-3) = -39
  \]
  \[
  -39 \times 5 = -195
  \]
  \[
  -195 \times 2 = -390
  \]
  This yields \(-390\).

- **Division:**
  \[
  13 \div (-3) \approx -4.33
  \]
  \[
  -4.33 \div 5 \approx -0.87
  \]
  \[
  -0.87 \div 2 \approx -0.435
  \]
  This yields \(-0.435\).

### Conclusion:
The only operation that makes sense with these numbers is addition. So, the operations are addition (+).

The expression is:
\[
13 + (-3) + 5 + 2 = 17
\]
