Given:
In a geometric sequence,
First term = 11
Common ratio = 4
To find:
The function for the geometric sequence.
Solution:
We have,
First term: a = 11
Common ratio: r = 4
We know that, nth term of a geometric sequence is
![a_n=ar^{n-1}](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn-1%7D)
Putting a=11 and r=4, we get
![a_n=(11)(4)^{n-1}](https://tex.z-dn.net/?f=a_n%3D%2811%29%284%29%5E%7Bn-1%7D)
The function notation is
![f(n)=(11)(4)^{n-1}](https://tex.z-dn.net/?f=f%28n%29%3D%2811%29%284%29%5E%7Bn-1%7D)
Therefore, the function for the geometric sequence is
, where n is a positive integer.
Let's see here... the answer is C just by using common sense. A doesn't make sense because you can't cube .4, as it is a percentage, and you wouldn't add that to 1000. B makes no sense because the percentage you are using is 4%, not 30%. Of course, just be sure to fact-check me there.
