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

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
