Answer:
Recursive formula for geometric sequence

is 
and explicit formula for geometric sequence
is

Step-by-step explanation:
Given sequence is 
To find the recursive and explicit formula for this sequence:
Let 
To find the common ratio r:




Therefore r=6



Therefore r=6
Therefore the common ration r=6
Therefore the given sequence is geometric sequence
Recursive formula for geometric sequence is 

and explicit formula is 



Therefore 
Answer:
(17, -13) (17, 8) --> In this problem, we use the y2-y1 over x2 - x1 formula.
Step-by-step explanation:
Step 1: Plug In--> <u>8-(-13)</u>
17 - 17
Step 2: Simplify: <u>21</u>
0
Answer: <em><u>Undefined. Vertical line on graph. </u></em>
13m-22=9m-6
13m-9m-22=-6
4m-22=-6
4m=-6+22
4m=16
m=16/4
m=4
<em>Therefore, m is 4</em>
