Any number that you choose can be the next number. It is easy to find a rule based on a polynomial of order 6 such that the first six numbers are as listed in the question followed by the chosen next number. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.
The simplest solution, based on a polynomial of order 5 is
t(n) = (-34n^5 + 565*n^4 - 3460*n^3 + 9575*n^2 - 11626*n + 5100)/60 for n = 1, 2, 3, ... and, accordingly, the next number in the sequence is 146.

The next number in the sequence is 27.
One answer would be 0.There is a pattern of half the number and subtract 2. 4/2 - 2 = 0.
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.

To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96

The next number in the sequence is 27.
Sequence is +4 - 3 + 5 - 2 + 6 - 1 (+1 - 1)2 6 3 8 6 12 next number 11
