What are the next three terms in the sequences below?
1.2, 5, 7, 12,
2.9, 11, 20, 31,
3. 2, 5, 10, 50,
4.1, 3, 3, 9,

27,243,6561 I think..might be wrong

Step-by-step explanation:

1,3,3,9,27,243,6561

because the first sequences were probably done by being multiplied by each other so for example:

1x3=3

3x3=9

the other 3 could be:

3x9=27

27x9=243

243×27=6561

table 3 represents a direct variation function. : )
