Question

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

This sequence has a
A.] common difference of 4
B.] common ratio of 4
C.] common difference of
`(1)/(4)`
D.] common ratio of
`(1)/(4)`

Answer 1

The answer would be the sequence has a common ratio of 4.
The explanation for this would be:
To get the common ratio for get the simplest form of the two numbers, so 12/3 = 4 and 48/12 = 4So we know that their common ratio is 4.
To check:
3 x 4 = 12
12 x 4 = 48
48 x 4 = 192
192 x 4 = 768
