3, 12, 48, 192, 768, . . this sequence has a a.] common difference of 4 b.] common ratio of 4 c.] common difference of d.] common ratio of

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

Aye bruh i don’t know this but someone else who smarter than us will answer this
