in table 1, each y value (number of rabbits) is increasing 3 times the previous month. for example 0 months=4 rabbits, 4 times 3 is 12, 1 month=12 rabbits. 12 times 3 is 36, 2 months=36 rabbits. 36 times 3 is 108, 3 months=108 rabbits. 108 times 3 is 324, 4 months=324 rabbits
0, 4
1, 12
2, 36
3, 108
4, 324
the second table is similar but instead of increasing times three, every number is doubled. to figure that out just take half of 24, which is 12, and then half of 12 is 6. therefore:
0, 6
1, 12
2, 24
3, 48
4, 96
