Answer:

A) No. It is an arithmetic sequence because you are subtracting by 3.

B) Yes. It is a geometric sequence because you are multiplying by 2.

Step-by-step explanation:

Arithmetic is addition or subtraction.

5 - 3 = 2 2 - 3 = -1 -1 - 3 = -4

Geometric is multiplication.

5 X 2 = 10 10 X 2 = 20 20 X 2 = 40
