Double it minus the previous number.

One of the infinitely many possible rules for the nth term of the sequence is t(n) = 4n - 1

The simplest, out of infinitely many possible answers, is the linear polynomial,U(n) = 4n - 1 for n = 1, 2, 3, ...

If you mean: 15 11 7 3 then the nth term is 19-4n

If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
