Answer:
The answer to your question is
Number of stickers = number of days + 3
Step-by-step explanation:
- To find the equation of the line that represents the situation, first, find the slope.
Slope = m =
m =
- Find the equation of the line
y - y1 = m(x - x1)
y - 4 = 1(x - 1)
y - 4 = x - 1
y = x - 1 + 4
y = x + 3
y = number of stickers
x = days
Number of stickers = number of days + 3
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.
