With a suitable choice of the generating rule, any number of your choice can be next.
A simple polynomial, though is
Un = (n3 - 8n2 + 11n + 36)/2 for n = 1, 2, 3, etc which gives the next number in the sequence as another 8.
10
49
485
The next number is 485.
The given sequence appears to have a common difference of 3. Thus, the next term in the sequence would be 17.
17?
The next number in the sequence is 27.
It is 5n+2 and so the next number is 22
44
It is 129.
Think it's 30...then 20
333
55
10
49
485
The next number is 485.
