Answer:
Common Difference: 
The ninth term: -1
Step-by-step explanation:
The sequence can be written like this,
3, 2.5, 2, 1.5, 1, ....
Here the common difference is clearly -0.5 or , and we can conclude that 
number is 
. So the 9th term is,
Answer: $2440.38
Step-by-step explanation:
Answer: infinite solutions
Step-by-step explanation:
(−3) (4) + (−3) (−3x) = 9x + −12
−12 + 9x = 9x + −12
9x − 12 = 9x − 12
9x − 12 − 9x = 9x − 12 − 9x
−12 = −12
−12 + 12 = −12 + 12
0 = 0
