Measure of angle 2 is 77. hope this helped.
Answer: B. 4
Step-by-step explanation:
The Fernandez family would have driven 208 miles in a rate of 4 hours.
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.
B I’m not 100% sure but I think
