Answer:
![c(n)=4\cdot(-\frac{1}{3})^{n-1}](https://tex.z-dn.net/?f=c%28n%29%3D4%5Ccdot%28-%5Cfrac%7B1%7D%7B3%7D%29%5E%7Bn-1%7D)
Explanation:
In the given geometric sequence:
![4,-\frac{4}{3},\frac{4}{9},-\frac{4}{27},\frac{4}{81},\ldots](https://tex.z-dn.net/?f=4%2C-%5Cfrac%7B4%7D%7B3%7D%2C%5Cfrac%7B4%7D%7B9%7D%2C-%5Cfrac%7B4%7D%7B27%7D%2C%5Cfrac%7B4%7D%7B81%7D%2C%5Cldots)
We see that:
• The first term, c1 = 4
Also:
![-\frac{4}{3}\div4=-\frac{4}{3}\times\frac{1}{4}=-\frac{1}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B3%7D%5Cdiv4%3D-%5Cfrac%7B4%7D%7B3%7D%5Ctimes%5Cfrac%7B1%7D%7B4%7D%3D-%5Cfrac%7B1%7D%7B3%7D)
• The common ratio, r= -1/3
The explicit formula for a geometric function is obtained using the formula:
![f(n)=a\cdot r^{n-1}](https://tex.z-dn.net/?f=f%28n%29%3Da%5Ccdot%20r%5E%7Bn-1%7D)
Substituting a (the first term, c(1)) and r, we have the explicit formula below:

given
900m = 2.700
m = 2.700 / 900
m = 0.003
