Question

Tell whether the sequence 1/3,0,1,-2… is arithmetic, geometric, or neither.

Find the next three terms of the sequence.

Answer 1

Any help

Answer 2

for a geometric series the common ration should be the same for two terms like
r=n2/n1=n3/n2
r=0/(1/3) is not equal to 1/0
so it is not a geometrc series

Answer 3

for a arithmetic series the common difference ashould be the same
d=n2-n1=n3-n2
d=0-1/3 is not equal to 1-0

conclusion it is neither arithametic nor geometric

Answer 4

did u get it
