There are not enough numbers to be certain.
The rule for the nth term could be
Subtract 6 from the previous term giving 30, 24, 18, etc
or
Multiply previous term by 0.8 giving 30, 24, 21.6, etc
etc

75. The sequence is:- multiply by three, divide by two, add one.
The next is 3.
To find the next number in the sequence 18, 24, 31, 24, 30, we can observe the pattern. The sequence alternates between increasing and then decreasing or stabilizing. The differences are +6, +7, -7, +6. Following this pattern, the next logical difference after +6 would be -7, which means we would subtract 7 from the last number, 30. Therefore, the next number in the sequence would be 30 - 7 = 23.
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 ruleUn = (7n5 - 129n4 + 891n3 - 2859n2 + 4298n - 1488)/24 for n = 1, 2, 3, ...the next number is 85.
81
The next number in the sequence is 48.
16
Think it's 30...then 20

182.25. 16 is square of 4, 36 is a square of 6, 81 is a square of 9. So the next term will be a squre.24=46, 54=69, therefore 121.5=9*x, then you will get x=13.5 and square of 13.5= 182.25 thats all

There appears to be a number missing in the sequence - as the difference of the differences is equal to 12 each time, apart from between 221 and 323, where the difference is 24.
