Each time you are subtracting 1/9 to get the next term
For example, going from term 2 to term 3 is a difference of -1/9
(1 8/9) - (1/9) = 1 7/9
which is why the answer is choice A
The factor of 12 is 1, 2 , 3 , 4 , 6 , 12
Hope it helps.
Answer:
D
Step-by-step explanation:
The formula we need to solve this is:

Where
is the distance from one focus to the vertex
is the second distance from another focus to same vertex
<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci
is half the length of the major axis (which is 9 here since total major axis is given as 18)
<em>Now we can plug into the equation and solve:</em>
<em>
</em>

<em>D is the correct answer.</em>
Answer:
Common ratio is 3
The three terms are 162, 486, 1458
Step-by-step explanation:
Given: The first 4 terms of a sequence are 
To find:
A. the common ratio
B. the next 3 values in the geometric sequence
Solution:
Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.
A.

So, the common ratio is 
B.
The next three values are as follows:

The answer is 4x-6. Good luck! :D
