You're on a roll — here are the solutions to the math problems: 1. The first term of the sequence above is 13. Each term after the first is 4 less than the previous term. What is the first negative number in the sequence? Step 1: Identify the first term and common difference. The first term is a_1 = 13. Each term is 4 less than the previous, so the common difference is d = -4. The formula for the n-th term of an arithmetic sequence is a_n = a_1 + (n-1)d. Step 2: Set up an inequality to find when the terms become negative. We want to find the smallest integer
