Question

true or false?
The following is a geometric sequence.
5, 3, 1, -1,…

Answer 1

geomtric sequence as in GP?

Answer 2

if so im pretty sure its an arithmetic progression (AP)

Answer 3

this sequence cannot be geometric as there is no multiplicative factor in between terms

Answer 4

so for it to be geometric it has to be multiplicative?

Answer 5

yes, there must be some sort of factor that is multiplied with each term of the sequence

Answer 6

and for it to be arithmetic it has to be additional?

Answer 7

an arithmetic sequence, on the other hand, means there is some sort of additive factor between each term.

Answer 8

yes

Answer 9

okay thank you so much!

Answer 10

that is what is happening here, like Crash said.
