Answer 1

Answer:

common ratio is 4

Step-by-step 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

$\frac{12}{3} =4$

$\frac{48}{12} =4$

$\frac{192}{48} =4$

So common ratio is 4
