The sequence given is 13, 1, 3, 9, 27...
Let's break it down:
- After the first number 13, the sequence starts with 1, which seems to be the starting point for the rest of the terms that follow.
- The sequence from 1:
- 1 (which is \(3^0\))
- 3 (which is \(3^1\))
- 9 (which is \(3^2\))
- 27 (which is \(3^3\))
The next term in the pattern of powers of 3 would be:
- \(3^4 = 81\)
Therefore, the next term in the sequence is 81.
