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.

45/75 = 30/x
30*75 = 2250/45 = 50
EF = 50 in.
2/3=14/21 and 5/7=15/21 so 14/21+15/21=29/21 or 1 and 8/21
