243
81 Each number is 3 x the previous number. So, 3 x 27 = 81.
-243
The next number is 243, because 81x3=243.
45
81
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
243
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.
Oh, what a delightful pattern you have there! It looks like each number is being divided by 3 to get the next number. So, starting with 243, if you divide by 3, you get 81. Then, if you continue dividing by 3, you get 27, and then 9. Keep exploring those numbers and see where they take you on your creative journey!
