To find the next term in the arithmetic sequence \(3, 9, 15,\), we first need to determine the common difference.

We subtract the first term from the second term:
\[
9 - 3 = 6
\]
Then, we subtract the second term from the third term:
\[
15 - 9 = 6
\]

The common difference \(d\) is \(6\).

Now, we can find the next term by adding the common difference to the last term in the sequence:
\[
15 + 6 = 21
\]

Thus, the next term of the arithmetic sequence is \(\boxed{21}\).
