by

The given series is 3, 9, 27, 81, 243. To find the next number, let’s analyze the pattern in the series.

First, we can look at how each number relates to the one before it:

  • 3 multiplied by 3 gives us 9
  • 9 multiplied by 3 gives us 27
  • 27 multiplied by 3 gives us 81
  • 81 multiplied by 3 gives us 243

As we can see, each number in the series is obtained by multiplying the previous number by 3. This indicates that the series follows a geometric progression where the common ratio is 3.

To determine the next number, we simply multiply the last number, 243, by 3:

243 x 3 = 729

Therefore, the next number in the series is 729.
