find the common ratio r for the geometric sequence and use r to find the next three terms 5,15,45,135

405

Step-by-step explanation:

r sequence = 5,15,45,135

d sequence:=10,30,90,270

r ratio is the Radio

d ratio is de Diameter

2*r=d

5*2=10, 15*2=30, 45*2=90, 135*2=270

to complete the sequence:

r+d = next r and continue

5+10=15

15+30=45

45+90=135

135+270=405
