Answer:
36x - 7
Step-by-step explanation:
Given:
The table for a geometric sequence.
To find:
The formula for the given sequence and the 10th term of the sequence.
Solution:
In the given geometric sequence, the first term is 1120 and the common ratio is:



The nth term of a geometric sequence is:

Where a is the first term and r is the common ratio.
Putting
, we get

Therefore, the required formula for the given sequence is
.
We need to find the 10th term of the given sequence. So, substituting
in the above formula.




Therefore, the 10th term of the given sequence is 2.1875.

-7 - 3x = 9x(x + 2)
Standard Form:
-9x^2 - 21x - 7 = 0
Your answer would be
-7-(-i)+6-3i
