urgent, please help, I really appreciate (100 points)Which sequence isn't a geometricprogression?​

Answer:3, 6, 9, 12 is not geometricStep-by-step explanation:A geometric progression has a common ratio r between consecutive terms.3, 6, 9 , 12has a common difference of 3 between terms and is arithmetic1, 5, 25, 125r = 5 ÷ 1 = 25 ÷ 5 = 125 ÷ 25 = 5 ← geometric4, 8, 16, 32r = 8 ÷ 4 = 16 ÷ 8 = 32 ÷ 16 = 2 ← geometric2, 6, 18, 54r = 6 ÷ 2 = 18 ÷ 6 = 54 ÷ 18 = 3 ← geometric
