B. geometric;7, -20, 61
C. arithmetic; -1/3,1 1/3,3

D. geometric;-3 1/3,-5 5/9,-9 7/27

Answer 2

just a barely educated guess but i say neither

Plug them into your formulas to find out for sure

Answer 3

It's definitely not arithmetic, since the differences are not common. It's not geometric because the ratio of the two successive terms does not even exist.

Answer 4

The ratio of the two successive terms \(1\) and \(0\) does not exist.
