Let's solve the expression step by step. The given expression is:

\[
2 - 5 + 24 - \frac{5}{2}
\]

### Step-by-step solution:
1. First, divide \( \frac{5}{2} \):
   \[
   \frac{5}{2} = 2.5
   \]

2. Now, rewrite the expression:
   \[
   2 - 5 + 24 - 2.5
   \]

3. Perform the addition and subtraction from left to right:
   \[
   2 - 5 = -3
   \]
   \[
   -3 + 24 = 21
   \]
   \[
   21 - 2.5 = 18.5
   \]

### Final answer:
\[
18.5
\]
