each of the points on the two graphs are of the form (n, tn), where tn is either a geometric or arithmetic sequence. identify the graph that presents a geometric sequence. justify your answers. then determine S8 of the geometric sequence

graph A points:

1,5

2,3

3,1

4,(-1)

5,(-3)

graph b points:

1,.5

2,1

3,2

4,4

5,8
