Question

someone refresh me on how to find out if something is a geometric sequence?

Answer 1

gs=1,3,9,27......

Answer 2

gs = 1 , 3 , 9 , 27.....

here each term is multiplied by 3

Answer 3

it is a gp

Answer 4

gphere we
find common

Answer 5

ratio

Answer 6

here we find common ratio (r)

r = t2/t1

Answer 7

If there is a common ratio r between each term, then it is a geometric sequence.

Answer 8

an=a*r^(n-1)

Answer 9

Just a tip to all the answerers: The question was asking how to determine if something is a GP or not. Not to start solving the question.
