Morning Kainyingi — let's get this done. Step 1: Identify the first term and the common difference. The number of cups sold on the first day is the first term, a_1. The increase in cups sold each subsequent day is the common difference, d. a_1 = 15 cups d = 8 cups Step 2: Use the formula for the n-th term of an arithmetic progression. The formula for the n-th term is a_n = a_1 + (n-1)d. We need to find the number of cups sold on the fourth day, so n=4. a_4 = a_1 + (4-1)d a_4 = 15 + (3) × 8 a_4 = 15 + 24 a_4 = 39 Maiwa sold 39 cups on the fourth day. The final answer is 39 cups.
