The given sequence is:

$3, 9, 27, 81, \dots$

This is a geometric sequence, where each term is obtained by multiplying the previous term by a constant factor (called the common ratio).

To find the common ratio $r$, we divide any term by its preceding term:

$r = \frac{9}{3} = 3$

Since the common ratio $r = 3$, we multiply the last term (81) by 3 to find the next term.

$\text{Next term} = 81 \times 3 = 243$

Solution:

The next term in the geometric sequence is 243.

Tip: In a geometric sequence, the ratio between consecutive terms remains constant throughout!
