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.
The simplest polynomial of order 6 is
Un = (-14n6 + 336n5 - 3185n4 + 15120n3 - 37436n2 + 45069n - 19170)/90 for n = 1, 2, 3, ...
Accordingly, the next term is -209.
You may, of course, be looking for a non-polynomial solution, and there are infinitely many of those.
11 comes next.
i think the answere is 38
It could be 11, or it could be 100, or 9.
17 cause it is the next prime number
nothing
11 comes next.
28 (add on the prime number 11)
11 comes after 10.
11
i think the answere is 38
The number 7 comes next.
10. I do believe it goes, 1,2,3 (skip one) 5,6,7 (skip one) 9,10,11
It could be 11, or it could be 100, or 9.
220
12
17 cause it is the next prime number
the patter is -2 +3 -4 +5 -6 +7 so it goes 8 6 9 5 10 4 11 3 12 2 11 1 10
