this would look like this: 0.0000001^10
If we were to do 0.0000001*0.0000001 it would be 0.00000000000010
We doubled the zeroes and moved the one up. Continue on until you reach the tenth power.

ANSWER
The 4th term is -27
EXPLANATION
The sum of the first n-terms of an arithmetic sequence is
![S_n= \frac{n}{2} (2a_1+d(n-1))](https://tex.z-dn.net/?f=S_n%3D%20%5Cfrac%7Bn%7D%7B2%7D%20%282a_1%2Bd%28n-1%29%29)
It was given that,
![S_4 = - 36](https://tex.z-dn.net/?f=S_4%20%3D%20%20-%2036)
![a_1 = 9](https://tex.z-dn.net/?f=a_1%20%3D%209)
![- 36= \frac{ 4}{2} (2 \times 9+d(4-1))](https://tex.z-dn.net/?f=%20-%2036%3D%20%5Cfrac%7B%204%7D%7B2%7D%20%282%20%5Ctimes%209%2Bd%284-1%29%29)
![-36=2(18+3d)](https://tex.z-dn.net/?f=-36%3D2%2818%2B3d%29)
![-18=18+3d](https://tex.z-dn.net/?f=-18%3D18%2B3d)
![-18 - 18 = 3d](https://tex.z-dn.net/?f=-18%20-%2018%20%3D%203d)
![3d = - 36](https://tex.z-dn.net/?f=%203d%20%3D%20%20-%2036)
![d = - 12](https://tex.z-dn.net/?f=d%20%3D%20%20-%2012)
The n-term is given by:
![a_n=a_1+ (n-1)d](https://tex.z-dn.net/?f=a_n%3Da_1%2B%20%28n-1%29d)
We substitute n=4 to get,
![a_4=9+ (4-1) \times -12](https://tex.z-dn.net/?f=a_4%3D9%2B%20%284-1%29%20%20%5Ctimes%20-12)
![a_4=9+ 3\times -12](https://tex.z-dn.net/?f=a_4%3D9%2B%203%5Ctimes%20-12)
![a_4=9 - 36](https://tex.z-dn.net/?f=a_4%3D9%20-%2036)
![a_4= - 27](https://tex.z-dn.net/?f=a_4%3D%20-%2027)
