<u>Geometric Sequence :</u>
Every term in a geometric sequence is obtained by multiplying the term before it by the same number. = is the general term for it. The common ratio is denoted by the number 'r'. Any term in the sequence can be used to find it by dividing it by the term before it.
'a' is the first term of the sequence, n is the term.
Given geometric sequence :
7 , -21 , 63 , ....
Here, first term = a = 7
common ratio = r = = -3
n = 15.
Then, term = = 7 x
= 7 x = 7 x 4,782,969
= 33,480,783 .

#geometric sequence
Answer:
32.3m
Step-by-step explanation:
Use equation A = Ao(0.5)^(t/t½)
Now input values: 40 = 980(0.5)^(t/7)
rearrange for t: t = [7ln(2/49)]/ / ln(0.5). Then from here, you can extract 32.3 as your answer
Plugging 10 for k in the expression gives us
We simplify this expression to
251 is your answer
