To determine the common ratio for a geometric sequence, we need to divide any term by its preceding term. If you have the sequence, please provide the terms so I can help calculate the common ratio.

However, if the terms of the sequence are not provided, let's assume it's a geometric sequence where we can use one of the options (A, B, C, or D) based on further information.

If you have the sequence, feel free to share it for a more precise answer.

Would you like more details on geometric sequences or their properties?

Here are 5 related questions:

1. How do you find the nth term of a geometric sequence?
2. What happens to a geometric sequence when the common ratio is greater than 1?
3. How do you sum the first n terms of a geometric series?
4. What is the difference between arithmetic and geometric sequences?
5. Can a geometric sequence have a negative common ratio?

Tip: In a geometric sequence, the common ratio can be found by dividing any term by the previous one, and it remains constant throughout the sequence.
