What is the nth term in the sequence 15 12 9 6 25?

The sequence you provided seems inconsistent, as it starts with a decreasing pattern (15, 12, 9, 6) and then jumps to 25, which breaks the sequence. The first four terms decrease by 3 each time, but without a clear pattern for the fifth term. If you intended to continue the sequence in a specific way, please clarify, and I can help determine the nth term.
