Answer:

Step-by-step explanation:
The common ratio is 
24, 12, 6, 3,
,
,
, 
so divide each term by 2

17/10-(2/5x2/2)
17/10-4/10
=13/10
3c/5-1/2=-31/2 Add 1/2 both sides
+1/2 +1/2
3c/5=-30/2 Then simplify the fraction
(5)3c/5=-15(5) Multiply 5 both sides
3c=75 Finally, divide by 3 both sides
c=25
So the answer to your question is E.
3(-1.5) + 4 = -0.5
3(0.5) + 4 = 5.5
