Answer:

Step-by-step explanation:
The explicit formula for a geometric sequence:

- n-th term
- first term
- common ratio

We have

The common ratio:

<h2>It's not a geometric sequence.</h2>
If
then the common ratio is 
Put to the explicit formula:

Put
and solve for <em>n </em>:


Answer:Any number less than -13.
Step-by-step explanation:
If the number is real and rational and non-natural, this means that it can be any number in the negative number space.
Additionally, since the number has to be less than -13, then the number could be any number less than -13.
With all these things considered, the number is any number less than -13 that is real and rational.

<u>Answer:</u>
a direct variation is a relation that is of the form <u>y = mx</u>
- example of a direct variation: y = 2x
a partial variation is is a relation that is of the form <u>y = mx+b</u>
- example of a partial variation: y = 2x + 1
- a non-linear function doesn't have a constant rate of change
- the graph for a non-linear relationship is curved
- a non-linear curve may show a positive or a negative relationship
