Answer
The common ratio is 3.
The next numbers in the sequence are: 81, 234, 729
Work Step by Step
The common ratio is 3 because each number in the sequence is 3 times more than the number before. In other words, each number in the sequence is multiplied by 3.
To find the next three numbers, simply multiply the last known number by 3 and then continue the pattern:
27 x 3 = 81
81 x 3 = 234
234 x 3 = 729
