Answer: 729
Explanation:
The pattern in the given list of numbers is that each number is obtained by multiplying the previous number by 3. Specifically:
- 3 x 3 = 9
- 9 x 3 = 27
- 27 x 3 = 81
- 81 x 3 = 243
So, to find the next number in the sequence, you would multiply 243 by 3:
243 x 3 = 729
Therefore, the next number in the sequence is 729.
