Determine if the sequence is algebraic or geometric, and find the common difference or ratio.

x 1 2 3 4

f (x) 3 9 27 81

Algebraic, common difference = 3

Algebraic, common difference = 6

Geometric, common ratio = 3

Geometric, common ratio = 6

Geometric

Common ratio=3

Step-by-step explanation:

3,9,27,81 is geometric because there is a common ratio.

We know there is a common ratio because a term divided by it's previous term is the same each time.

That is

81/27=3

27/9=3

9/3=3.

So the common ratio is 3.
