Question

Algebra 2 please help, I'll give you a medal :)

Answer 1

Where's the question lol

Answer 2

Given a geometric sequence in the table below, create the explicit formula and list any restrictions to the domain.
n a_n
1 -4
2 20
3 -100

A. a_n = −5(−4)^(n − 1) where n ≥ 1

B. a_n = −4(−5)^(n − 1) where n ≥ 1

C. a_n = −4(5)^(n − 1) where n ≥ −4

D. a_n = 5(−4)^(n − 1) where n ≥ −4

Answer 3

you know now how to find common ratio ?

Answer 4

No?

Answer 5

common ratio r = 2nd term /1st term = 3rd term /2nd term = ...and so on
now can you find ?

Answer 6

I'm not sure but I think the answer is A..

Answer 7

its not A

Answer 8

the general term is \(\large a_n = a_1 r^{n-1}\)
a1 = 1st term
r= common ratio
