This is a geometric sequence, where each term is multiplied by a constant to get the next term.

Step 1: Identify the common ratio.
In this case, each term is multiplied by 3 to get the next term.

Step 2: Apply the common ratio to the last term.
The last term given is 81. Multiply 81 by 3.

81 * 3 = 243

So, the next number in the series is 243.
