81 Each number is 3 x the previous number. So, 3 x 27 = 81.
-243
The number pattern is a sequence where each number is divided by 3 to get the next number. Following this pattern, the next numbers would be 9 (27 ÷ 3), 3 (9 ÷ 3), and 1 (3 ÷ 3). Thus, the complete sequence continues as 9, 3, and 1.
The next number is 243, because 81x3=243.
45
Each number is one third of the previous number, the next number in the series would be 3
Next number= 27 X 3 = 81.
If you mean: 1 3 9 27 81 then it is 3*81 = 243
81 Each number is 3 x the previous number. So, 3 x 27 = 81.
For each term, multiply the previous by -3. So, 27*-3=-81. -81 is the next term.
243
-243
The number pattern is a sequence where each number is divided by 3 to get the next number. Following this pattern, the next numbers would be 9 (27 ÷ 3), 3 (9 ÷ 3), and 1 (3 ÷ 3). Thus, the complete sequence continues as 9, 3, and 1.

It is 3 times 81 = 243
9 243 - 81 = 162 81 - 27 = 54 162 = 54 * 3 54 = 18 * 3 27 - 18 = 9
The next number is 243, because 81x3=243.
