Question

What is the common ratio of the following geometric sequence? 6, 9, 27/2, 81/4,...​

Answer 1

r = 3/2

Explanation:

1.5 written as a fraction is 3/2

Answer 2

1.5

Explanation:

To find the common ratio of a geometric sequence, you divide two consecutive terms together. You can start by dividing 9/6, or 1.5. To confirm this is the common ratio, you can divide 27/2 ÷ 9, which is indeed 1.5. The common ratio is the multiplier of the sequence, so it is consecutive and does not change throughout the function.
