Answer:

In a geometric sequence, the common ratio between consecutive terms is constant.

Step-by-step explanation:

In a geometric sequence, the common ratio between consecutive terms is constant.

The n-th term of a geometric sequence with first term [tex]a[/tex] and common ratio [tex]r[/tex] is represented by the formula:

[tex]a_{n}=a\,r^{n-1}[/tex]

For example,

[tex]1, -3, 9, -27, 81, -243, ...[/tex]

As the common ratio 'r' between consecutive terms is constant.

  • r = -3/1 = -3
  • r = 9/-3 = -3
  • r = -27/9 = -3
  • r = 81/-27 = -3
  • r = -243/81 = -3

So, the common ratio between consecutive terms is constant i.e. -3. Thus, it is a geometric sequence with a common ratio -3.
