Accepted Solution
A:
Answer: d. 0.2; 0.08, 0.016, 0.0032Step-by-step explanation:The common ratio is the ratio of adjacent terms: r = 2/10 = 0.4/2 = 0.2__Multiplying the last term by this ratio gives the next term: 0.4×0.2 = 0.08 0.08×0.2 = 0.016 0.016×0.2 = 0.0032The next 3 terms are 0.08, 0.016, 0.0032.
