Question

Find the common ratio of the geometric sequence. -8,2,-(1)/(2),ldots

Answer 1

To find the common ratio of a geometric sequence, we need to divide any term in the sequence by the previous term.Let's take the second term and divide it by the first term:

Now, let's verify this by checking the ratio between the third term and the second term:

Since the ratio is consistent between consecutive terms, the common ratio

of the geometric sequence is:
