Question

Determine if the sequence below is arithmetic or geometric and determine the common difference/ratio in the simplest form. 180,\, 30,\, 5,\..

Answer 1

geometric sequence

Explanation:

A geometric sequence has a common ratio r between consecutive terms.

Here r =
`(30)/(180)` =
`(5)/(30)` =
`(1)/(6)`

Then sequence is geometric
