Determine the ratio of the geometric sequence: 1/10, -1/2, 5/2,...-1/51/5-55
Accepted Solution
A:
Answer: third option.Step-by-step explanation: By definition we know tht the geometric sequences has a common ratio, which is represented with r. This ratio can be calculated by dividing a term by the previous term. Therefore, keeping the information above on mind, you have that the ratio r of the geometric sequence given in the problem, is the shown below: [tex]r=\frac{-\frac{1}{2}}{\frac{1}{10}}\\\\r=-5[/tex]
