Help me please someone

Answer 1

Answer:

B is Geometric and its next terms are 81, 243, 729...

See example below to complete other problems.

Step-by-step explanation:

Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Problem B is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.

Example: 27-9= 18                27/9 = 3

               9-3 = 6                   9/3 = 3

etc. Common ratio of 3
