$10.22 this is the answer for you..............
You did not write the question correctly but I will try to answer the question according to 2 possible interpretations of your question.
Case 1:
Given the geometric sequence:
![4,\ \frac{4}{5} ,\ \frac{4}{25} ,\ \frac{4}{125} ,\ .\ .\ .](https://tex.z-dn.net/?f=4%2C%5C%20%20%5Cfrac%7B4%7D%7B5%7D%20%2C%5C%20%20%5Cfrac%7B4%7D%7B25%7D%20%2C%5C%20%20%5Cfrac%7B4%7D%7B125%7D%20%2C%5C%20.%5C%20.%5C%20.)
Common ratio is given by
![r= \frac{2nd\ term}{1st\ term} = \frac{ \frac{4}{5} }{4} = \frac{1}{5}](https://tex.z-dn.net/?f=r%3D%20%5Cfrac%7B2nd%5C%20term%7D%7B1st%5C%20term%7D%20%3D%20%5Cfrac%7B%20%5Cfrac%7B4%7D%7B5%7D%20%7D%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B5%7D%20)
The explicit rule of a geometric sequence is given by
![T_n=ar^{n-1}](https://tex.z-dn.net/?f=T_n%3Dar%5E%7Bn-1%7D)
Therefore, the explicit rule of the given sequence is
![T_n=4\left( \frac{1}{5} \right)^{n-1}\ or\ 20\left( \frac{1}{5} \right)^n](https://tex.z-dn.net/?f=T_n%3D4%5Cleft%28%20%5Cfrac%7B1%7D%7B5%7D%20%5Cright%29%5E%7Bn-1%7D%5C%20or%5C%2020%5Cleft%28%20%5Cfrac%7B1%7D%7B5%7D%20%5Cright%29%5En)
Case 2:
Given the geometric sequence:
![4,\ 4\cdot5,\ 4\cdot25,\ 4\cdot125,\ .\ .\ .](https://tex.z-dn.net/?f=4%2C%5C%204%5Ccdot5%2C%5C%204%5Ccdot25%2C%5C%204%5Ccdot125%2C%5C%20.%5C%20.%5C%20.)
Common ratio is given by
![r= \frac{2nd\ term}{1st\ term} = \frac{4\cdot5}{4} = 5](https://tex.z-dn.net/?f=r%3D%20%5Cfrac%7B2nd%5C%20term%7D%7B1st%5C%20term%7D%20%3D%20%5Cfrac%7B4%5Ccdot5%7D%7B4%7D%20%3D%205%20)
The explicit rule of a geometric sequence is given by
![T_n=ar^{n-1}](https://tex.z-dn.net/?f=T_n%3Dar%5E%7Bn-1%7D)
Therefore,
the explicit rule of the given sequence is
Answer:
Wheres the picture so show the measurements
Step-by-step explanation:
Harrison ate n=4/4 slices of pizza.
Explanation
4 friends evenly divided up a -slice pizza.
So, the number of slices each friend received
Now, Harrison ate 1 fewer slice than he received. As he received slices, so 1 fewer than means......
Thus, Harrison ate n=4/4 slices of pizza.
