It is impossible to say what sequence comes after the given set of numbers. What I can do is to suggest what number might come next in the given sequence.
Using the rule
Un = (7n5 - 129n4 + 891n3 - 2859n2 + 4298n - 1488)/24 for n = 1, 2, 3, ...
the next number is 85.
22
31.
31
(1) Take the difference of the two previous numbers in sequence (2) Add 4 to this difference. (3) Take the number from step #2 and add it to the previous number in the sequence. For example, to find the next number in the sequence: (1) 121 - 90 = 31 (2) 31 + 4 = 35 (3) 121 + 35 = 156
It is: 9

158 One possible sequence is t(n) = 0.5*(19n2 - 7n + 40) for n = 1, 2, 3, ...
If you are adding one to the number you subtract each time, then 31 would be the next number. 46 - 1 = 45 45 - 2 = 43 43 - 3 = 40 40 - 4 = 36 36 - 5 = 31, etc...
the number that comes after 30 is 31 then it's 32, 33, 34, 35, 36, 37, 38, 39, then finally it's 40
40.
9 = 13 - 4 = 22 - 13 = 31 - 22 = 40 - 31 next are 49 58 67 76 85 94 and so on ...
