public interface IntSequence
{
    public int next();
}

public class C {
   public IntSequence() getSequenceGenerator(final int start, final
int increment) {
       return new IntSequence() {
           int current = start;
           public int next()
           {
            int ret = current;
            current += increment;
            return ret;
        };
    }
}

The point I'm trying to make:
The concept of a "Sequence generator" is obviously inherently
stateful. Every invocation of its parameterless method is meant to
yield a different value. IMHO, this is best modelled by means of a
designated interface, not by a lambda.
