Step-by-step explanation:You have a geometric sequence starting with 8, 64, _, _.In a geometric sequence, each term is found by multiplying the previous term by a constant ratio (r). Step 1: Find the common ratio (r)Given the first two terms: 8 and 64.r = (second term) ÷ (first term) = 64 ÷ 8 = 8 Step 2: Find the next two termsThird term = second term × r = 64 × 8 = 512Fourth term = third term × r = 512 × 8 = 4096 Answer:The sequence is: 8, 64, 512, 4096
