For Exercises 45–50, write out the first three terms and the last term. Then use the formula for the sum of the first n terms of an arithmetic sequence to find the indicated sum.

Verified step by step guidance

1. Identify the sequence: The given expression is \( \sum_{i=1}^{17} (5i + 3) \), which represents an arithmetic sequence.
2. Find the first term: Substitute \( i = 1 \) into the expression \( 5i + 3 \) to get the first term.
3. Find the second term: Substitute \( i = 2 \) into the expression \( 5i + 3 \) to get the second term.
4. Find the third term: Substitute \( i = 3 \) into the expression \( 5i + 3 \) to get the third term.
5. Find the last term: Substitute \( i = 17 \) into the expression \( 5i + 3 \) to get the last term.
