The next number is 54. The sequence is generated by the rule: Un = (n4 - 11n3 + 51n2 - 107n + 102)/4 for n = 1, 2, 3, ... and U6 = 54.
216, 432, 864.... Just keep multiplying the number by 2.
It is 1000.
333
The pattern looks like the previous number is multiplied by -3, hence the next number in the sequence would be (-54) x (-3) = 162

The next number is 54. The sequence is generated by the rule: Un = (n4 - 11n3 + 51n2 - 107n + 102)/4 for n = 1, 2, 3, ... and U6 = 54.
Chromium has 5 isotopes with mass numbers ranging in sequence from 50 to 54.
