Answer:
1 ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
Note there is a common ratio between consecutive terms, that is
10 ÷ 20 = 5 ÷ 10 = 2
÷ 5 = ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Thus to obtain the next term in the sequence multiply the previous term by ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
2
×
= 1 ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)

Answer: 13. -68
14. 36
15. -36
16. -3
17. 10
18. -4
19. 1310 ft
20. 330 ft
Step-by-step explanation:
13. 34*(-2)=-68
14. -9*(-4)=
-(9*(-4))=
-(-36)=36
15. 12*(-3)=-36
16. -12/4=-3
17. -20/(-2)=
20/2=10
18. 200/(-50)=-4
19. -1640*(-1)-(-330*(-1))=
1640-(-330*(-1))=
1640-330=1310 ft
20. -990*(-1)-(-660*(-1))=
990-(-660*(-1))=
990-660=330 ft
