1.) 3, -6, 12, -24,....
2.) -1, 5, -25, 125,....

Answer 1

sequence will be geometric when the ratio of next term to previous term will be constant throughout ...
so, for 1.)
is
-6/3 = 12/-6 = -24/12 =.....

Answer 2

i mean are all those ratios equal ?

Answer 3

that was alll wrong

Answer 4

again!

Answer 5
