Determine whether the following sequence is arithmetic, geometric, or neither. -7, -14, -28, -56,

Explanation:

To go from term to term, we are multiplying by 2

-7 * 2 = -14

-14 * 2 = -28

-28 * 2 = -56

This means the common ratio is 2 and this sequence is geometric.

Alternatively, you can divide each term by its prior term

-56/(-28) = 2

-28/(-14) = 2

-14/(-7) = 2

Each time we get the same result showing the common ratio is 2.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
