Question

I keep getting a step wrong because I’m getting a radio that isn’t on here..

Answer 1

3

Explanation:

Geometric sequence:

`\sf Common \ ratio = ((n+1)^(th) \ term)/(n^(th))`

`\sf = (8^(th) \ term)/(7^(th) \ term)\\\\\\ =(213)/(77)\\\\\\=3`

Answer 2

Given:-

7th term is 77 and 8th term is 231.

To find:-

The common ratio.

Now to find the common ratio we divide both the numbers. we get,

`(231)/(77)=3`

So the common difference is 3.

So the common ratio is 1/3.
