To find the common ratio of a geometric sequence, you can divide any term by the previous term.

In the sequence given: 2, 6, 18, 54, ...

Let's calculate the common ratio (r):

1. Divide the second term by the first term:
\( r = \frac{6}{2} = 3 \)

2. Divide the third term by the second term:
\( r = \frac{18}{6} = 3 \)

3. Divide the fourth term by the third term:
\( r = \frac{54}{18} = 3 \)

In each case, the common ratio r is 3.

Therefore, the common ratio is **3**.
