Answer: A is (arithmetic sequence)
and D is 1 2 3 4 5 6 7
Unfortunately, I only know the answer to those two.
Sorry.
Answer:it depends what was on it but i would say about 500
Step-by-step explanation:
The sequence is an geometric progression;
Nth=a₁r^(n-1)
a₁ is the first term=-1
r=ratio=a₂/a₁=6/-1=-6
Nth=-1(-6^(n-1)
NTh=an
a₁=-1(-6⁰)=-1
a₂=-1(-6¹)=6
a₃=-1(-6²)=-36
a₄=-1(-6³)=216
therefore this serie is rising at an increasing fast speed, it is an geometric progression.
Pick any number. Multiply the 7 and the 11 both by it,
and you'll have an equivalent ratio.
Examples:
(by 2) . . . 14 to 22
(by 6) . . . 42 to 66
(by 10). . . 70 to 110
(by a million) . . . 7 million to 11 million
he initial number of trees was 204.
<h3>How to find the initial number of trees?</h3>
The first step to finding the initial number of trees is to write an equation that represents the situation.
- T is equal to the initial number of trees.
- 5 trees were removed = t - 5
- Each tree produces 210 oranges = (t-5) (210)
- The total of oranges is 41,780 = (t-5) (210)= 41,780
- (t-5) (210)= 41,780
- t-5= 41,780 / 210
- t-5 = 198.95
- t = 198.95 + 5
- t = 203.9
This number can be rounded as 204.
