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 next number is 17 because each number is increasing by increments of 3
17?
The next number in the sequence is 27.
It is 5n+2 and so the next number is 22
44
Think it's 30...then 20
It is 129.
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
