Answer:
.5299192646
Step-by-step explanation:
Just plug it in a calculator
Given:
The geometric sequence is:

1 -4
2 20
3 -100
To find:
The explicit formula and list any restrictions to the domain.
Solution:
The explicit formula of a geometric sequence is:
...(i)
Where, a is the first term, r is the common ratio and
.
In the given sequence the first term is -4 and the second term is 20, so the common ratio is:



Putting
in (i), we get
where 
Therefore, the correct option is B.
Answer:
B) {-2, 2, 5}
Step-by-step explanation:
Coordinate points on the graph
(1,5), (3,5) , (4,2) and (6, -2)
Range is a list of y values so in this case range is:
{-2, 2 , 5}
