If a1=-2 then what is an= 2an-1-3 in the fourth term

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

-2x-4

step-by-step explanation:

below

step-by-step explanation:

1. 5/1

2. 10/16

3. 90/2

4. 1/20

5. 3/1

6. 14/24

7. 1/4

8. 18/10

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
