Answer
Are you taking the quiz for math 1? This bout to be real awkward if you aren't who I think you are :/
Step-by-step explanation:
Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term
can be obtained as the previous term
by a constant value called the common ratio.

or equivalently

Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6
Communitive property is the property that allows you to move the numbers around in addition and multiplication.
For example:
(addition) 1 + 2 = 2 + 1
(multiplication) 3 x 4 = 4 x 3
This property cannot be used in division or subtraction
A command economy tends to exist under a socialist government that provides a lot of regulation. In a command economy system central government controls the larger part of the economic system. Have a nice day :)
Is the answer 15? If not are there any options?
