Answer:
3, 5, 8, 9, 12
60, 100, 160, 180, 240
Step-by-step explanation: the only values that you have full information for is the first column
3, 60
to get from 3 to 60 you would multiply by 20, so for the next column multiply 5 by 20 to get 100
then 8, 160
for the fourth column you would just divide 180 by 20, 9
and finally for the last column you would multiply 12 by 20 to get
240
