Without a sequence given in the question, the next number to 6 is 7.
The next number in the sequence 3-15-6-30-21 is -207.
The next is 3.
The nest number in the sequence is 18. Note that the difference between each number and the next number in the sequence follows the simple sequence of 1,2,3,4. Obviously the next in the sequence of increases is 5, so 13+5=18.

Well, isn't that just a delightful little sequence you've got there! Let's take a closer look at it. If we look at the pattern, we can see that each number is getting multiplied by the next odd number. So, the next number in the sequence would be 28 multiplied by 6, which gives us 168. Happy little numbers, just dancing along in a lovely sequence!
