Answer: 243, 729

Explanation:

We can see that the pattern is each number is multiplied by 3.

1 x 3 = 3

3 x 3 = 9

9 x 3 = 27

27 x 3 = 81

This means that to continue, we'll need to multiply 81 by 3, and multiply the product of that by 3.

81 x 3 = 243

243 x 3 = 729

This means that 243 and 729 is our final answer.
