Question

Determine whether the sequence could be geometric or arithmetic. If possible, find the common ratio or difference. 
1/4, 1/12, 1/36, 1/108

anonymous · Answer

it is geometric, with a common ratio of 1/3

anonymous · Answer

1/4 * 1/3 = 1/12

1/12 * 1/3 = 1/36 etc...

anonymous · Answer

Oh I see. Okay thank you! :) @robz8

anonymous · Answer

Arithmetic would deal with the common difference. 
And it would have been like adding or subtracting the same number from each term. 

Geometric would deal with the common ratio. 
And it would have been like dividing and multiplying the same number from each term.

anonymous · Answer

And yes the common ratio would be $$\frac{ 1 }{ 3 }$$
