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.
-29/6<x<25/6
I'm sorry I can't graph because Brainly won't take my Img.
But I will tell you that it is a closed circle.
I hope you don't find the solution too messy. If there is anything you don't get. Let me know and I will explain it:
Yes. since half of 50 is 25 it is correct to say that 18 is less than half
