The next number is 243, because 81x3=243.

The series alternates between two patterns: one where numbers are multiplied by 3 and then reduced (18 to 27 to 36) and another where numbers are multiplied by 4 and then reduced (81 to 72 to 63). Following this pattern, the next number after 36 (from the first sequence) would be 45 (36 multiplied by 1.25), and after 63 (from the second sequence), the next number would be 54 (63 reduced by 9). Thus, the next number in the series is 45.
The pattern in the sequence 3, 9, 27, 81 is that each number is multiplied by 3 to get the next number. Therefore, the next number after 81 would be 81 × 3 = 243. Following that, the subsequent number would be 243 × 3 = 729. Thus, the next two numbers in the pattern are 243 and 729.
81 Each number is 3 x the previous number. So, 3 x 27 = 81.

It is '3' to the power(exponent) of 'n-1'. #1 ; 3^(1-1) = 3^(0) = 1 #2 ; 3^(2 -1) = 3^(1) = 3 #3 ; 3^(3-1) = 3^(2) = 9 #4 ; 3^(4-1) = 3^(3) = 27 #5 ; 3^(5-1) = 3^(4) = 81 #6 ; 3^(6-1) = 3^(5) = 243 #n th term ; 3^(n - 1) et seq.,

Each number is one third of the previous number, the next number in the series would be 3
Next number= 27 X 3 = 81.
729 is the next number in the sequence. You times each number by the past number times by three e.g. 3x3=9, 9x3=27, 27x3= 243, 243x3=729
The pattern in the sequence 3, 9, 27, 81 is that each number is multiplied by 3 to get the next number. Therefore, the next number after 81 would be 81 × 3 = 243. Following that, the subsequent number would be 243 × 3 = 729. Thus, the next two numbers in the pattern are 243 and 729.
81 Each number is 3 x the previous number. So, 3 x 27 = 81.
243 each number is 3 times larger than previous 1 x 3 = 3 3 x 3 = 9 9 x 3 = 27 27 x 3 = 81 81 x 3 = 243
For each term, multiply the previous by -3. So, 27*-3=-81. -81 is the next term.
