The explicit formula for a certain geometric sequence is f(n)=1250(11)^n-1. What is the exponential function for the sequence? W

Agata [3.3K]

Answer:

$f(n) = \frac{1250}{11}(11)^n$

Step-by-step explanation:

Given

$f(n) = 1250(11)^{n-1}$

Required

Write as exponential function

An exponential function is represented as:

$f(n) = ab^n$

$f(n) = 1250(11)^{n-1}$

Apply law of indices

$f(n) = \frac{1250(11)^n}{11}$

$f(n) = \frac{1250}{11}(11)^n$

<em>The above represents the exponential function</em>

I don't get how I got it right. I have a test upcoming and I am really confused

aleksandr82 [10.1K]

You have a system of linear equations. For solving this question, you can apply the addition method.

In this method, we try to cancel one of the variables x or y. Let`s go!

Now, you should replace the value found for x in any equation for finding y.

Answer

x=5 and y=-2
