<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:


The square root is having a sum, ex: 16 and you need to find 2 numbers that are the same numbers and multiply them together and their value equals the said number. Answer: 4 because 4×4=16

<u>Vertical:</u> M and I
Vertical angles: A pair of opposite angles that are made by two intersecting lines.
<u>Complimentary:</u> None
Complimentary angles: A pair of angles whose sum is equal to 90°.

Answer:
8/8
Step-by-step explanation:
There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).
Basically, multiply how many fourths (four per pie) by how many pies there are.
4 x 2 = 8
There are 8 pieces.
