Question
**Find the indicated sum.**

\[ 
\sum_{i=1}^{5} i(i + 4) 
\]

---

\[
\sum_{i=1}^{5} i(i + 4) = \boxed{\phantom{answer}} \quad (\text{Simplify your answer.})
\]

**Explanation:**

The given expression is a summation notation, indicating that you need to calculate the sum of a sequence from \(i = 1\) to \(i = 5\). The expression inside the summation is \(i(i + 4)\), meaning for each integer value of \(i\) from 1 to 5, you substitute \(i\) into the expression, calculate the result, and then sum all the results.
