Given any number it is easy to find a rule based on a polynomial of order 7 such that the first seven numbers are as listed in the question and the next is the given number. There are also non-polynomial solutions.
The simplest solution, using a polynomial of order 6, is
Un = -0.0069n6 + 0.1708n5 - 1.6319n4 + 7.6458n3 - 18.3611n2 + 23.1833n - 10 for n = 1, 2, 3, ...
Accordingly, the next term is 11.

what number comes next 1 -8 -16 -24 -33
Probable answer is 11 as shown below:1 + 5 = 65 + 6 = 116 + 11 = 1711 + 17 = 28
It's a pattern of odd numbers- so... nine is next, then eleven, and so on. 1-3-5-7-9-11....
