Answer: 243, 729, 2187 :)
Step-by-step explanation: you can see in this sequence that each term is multiplied by 3 in order to produce the next term. (ex. 3 • 3 = 9) to find the next three terms simply multiply 81 by 3 and it's product by three and so on. Your work would be something like this: (81 • 3 = 243) (243 • 3 = 729) (729 • 3 = 2187).
