Determine whether each sequence is arithmetic or geometric. Find the next three terms.
4, 8, –16, 32, . . .
A.arithmetic, 64, 128, 256
B.geometric, –64, 128, –256
C.geometric, –48, 64, –80
.DThe sequence is neither geometric nor arithmetic.
I think it's B...?
81, 27, 9, 3, . . .
A.arithmetic, 0, –3, –6
B.geometic, 0, –3, –6
C.geometric, 1,1/3 , 1/9
D.The sequence is neither geometric nor arithmetic.
I know they are dividing by 3...but I am not sure if this is A or D...?

Reiny
If for your given terms, the first term is 4
then it would be geometric.
Probably just a typo, if so
then r = 2 , and your choice of B would be correct
for the second, it is geometric , and yes, they are dividing by 3, so r = 1/3
let's keep going
81 27 9 3 1 1/3 1/9
so it is C

Thank you Reiny and it was a typo....thanks..

tessa
shes right both are correct just got a 100
