Answer 2

What does geometric sequence mean?

Answer 3

A sequence of numbers where each term after the first is found by multiplying the previous one by a non-zero number called the common ratio.

Answer 4

Good.
Since each term starting with the second term is found by multiplying the previous term by the common ratio, then you can find the common ratio by dividing any term by the previous term.

Answer 5

Choose any two consecutive terms, and divide the second one by the first one.
No, that is not it.
