R/9 = -21
Multiply by 9
r = -189
Using limits, it is found that the infinite sequence converges, as the limit does not go to infinity.
<h3>How do we verify if a sequence converges of diverges?</h3>
Suppose an infinity sequence defined by:

Then we have to calculate the following limit:

If the <u>limit goes to infinity</u>, the sequence diverges, otherwise it converges.
In this problem, the function that defines the sequence is:

Hence the limit is:

Hence, the infinite sequence converges, as the limit does not go to infinity.

Answer:
54
Step-by-step explanation:
x-1=3
2xy=24
3+24=27
27·2=54
So you're looking for the answer? If so, it is -3/4
Answer:
f(-)=29/11
Step-by-step explanation:
Even though you don't want an explanation, I'll just tell you the basics lol.
So what you have to do, is plug in -7 for the x's.
it should look something like the equation below.

After that all you need to is just to subtract :)

Then after that all you need to do is just let the negatives cancel out each other so you should get:

Hope this helps!
