<u>Geometric Sequences</u>
There are two basic types of sequences: arithmetic and geometric. The arithmetic sequences can be recognized because each term is found as the previous term plus a fixed number called the common difference.
In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
We are given the sequence:
112, -28, 7, ...
It's easy to find out this is a geometric sequence because the signs of the terms are alternating. If it was an arithmetic sequence, the third term should be negative like the second term.
Let's find the common ratio by dividing each term by the previous term:

Testing with the third term:

Now we're sure it's a geometric sequence with r=-1/4, we use the general equation for the nth term:


For this case, we find the equation of the line of the form:

Where:

So, we have:

We substitute one of the points:
Thus, the equation is:

Now, we substitute a point belonging to the region to determine the sign.
(
-3 is less than 0.
Then, the inequality is:

As the border of the region is dotted, then it remains ">."
