Answer:
2 1/24
Step-by-step explanation:
2/3 = 16/24
3/4= 18/24
5/8= 15/24
16+18+15=49
49-24= 25-24=1
2 1/24

Answer:
1000 times larger.
Step-by-step explanation:
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.
