3 / 81 = 3 / 3 ∙ 27 = 1 / 27
( 1 / 9 ) / 3 = 1 / 27
Answer B.
The sequence is geometric because it decreases by a factor of 1 / 27
hi im really stuck...
3. which explains why the sequence 81,3,1/9....... is arithmric or geometric
A. the sequence is arithmic because it decreases by a factor of 1/27
B. the sequence is geometric because it dereases by a factor of 1/27
C. the sequence is arithmeric because it decreases by a factor of 3
D. the sequence is geometric because it decreases by a factor of 3
