Answer:
common ratio is 4
Step-by-step explanation:
3, 12, 48, 192, 768, . . .
LEts find the common difference
[tex]12-3= 9[/tex]
[tex]48-12= 36[/tex]
There is no common difference
LEts find out common ratio by dividing the second term by first term
[tex]\frac{12}{3} =4[/tex]
[tex]\frac{48}{12} =4[/tex]
[tex]\frac{192}{48} =4[/tex]
So common ratio is 4
