-6, and then 13.

11 comes next.
-11 Pattern: Subtract 1, subtract 2, subtract 3 and so on.
4 6 3 6 12 14 11 14
Notice the pattern: 12^2 11^2 10^2 9^2 .. So the next term is 6^2=36
12
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
8 7 10 11 13. 13256 is 5 numbers, in a combination.

42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
