Answer:

You gave the explicit form.
Step-by-step explanation:
You gave the explicit form.
The recursive form is giving you a term in terms of previous terms of the sequence.
So the recursive form of a geometric sequence is
and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
r is the common ratio and can found by choosing a term and dividing by the term that is right before it.
So here r=-3 since all of these say that it does:
-54/18
18/-6
-6/2
If these quotients didn't match, then it wouldn't be geometric.
Anyways the recursive form for this geometric sequence is

Answer:
3.71 cm
Step-by-step explanation:
Hi there!
Area of a circle equation:
where r is the radius
Plug in the area 43.25 cm²

Divide both sides by π to isolate r²

Take the square root of both sides to isolate r

Therefore, the length of the radius rounded to 2 decimal points is 3.71 cm.
I hope this helps!
so since only 3 out of 11 went to visit then it is simple
since just 3 went and there were 11
3/11 of the students went
