b. common ratio of 4
c. common difference of 1/4
d. common ratio of 1/4

Answer 1

the sequence has a common difference of 4.

Answer 2

common ratio is 4

Explanation:

3, 12, 48, 192, 768, . . .

LEts find the common difference

`12-3= 9`

`48-12= 36`

There is no common difference

LEts find out common ratio by dividing the second term by first term

`(12)/(3) =4`

`(48)/(12) =4`

`(192)/(48) =4`

So common ratio is 4
