Using the simplest polynomial of order 4, Un = (-23n4 + 266n3 - 1033n2 + 1630n - 32)/24, for n = 1, 2, 3, ... the next number will be 22.

The difference between the numbers is increasing by 3 each time. Therefore, after a difference of 15 comes a difference of 18, therefore, the next number is 47 + 18 = 65.
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.
