It is impossible to identify any pattern from one number.
Click below.
A single number, such as 32168421 does not make a pattern!
The pattern is multiply by -1, add 5, repeat. The next three numbers are: -7, -2, 2
The difference between the successive numbers is 4. so the next three numbers could be 4, 0 and -4.
It appears as if the pattern is doubling, therefore the next three numbers are 16, 32, and 64.

Numbers with three factors are squares of primes. So: 4, 9, 25
There are infinitely many such numbers and they do not form any systematic pattern.

the next three numbers are 180 540 and 1620=)
The difference between the successive numbers is 4. so the next three numbers could be 4, 0 and -4.

32;64;128
One number, such as 23266992 does not for a sequence.
-17, -22
