There seems to be no logical order to this set of numbers.
* * * * *
Or, you could try 78.
Fit the quartic polynomial
t(n) = (7n4 - 66n3 + 221n2 - 186n + 216)/24 for n = 1, 2, 3, ...

29, assuming it is an algebraically reclusive sequence.
18-the correct number should be 20.
The series appears to be following a pattern where each number is the result of a mathematical operation on the previous numbers. In this case, the pattern seems to be adding consecutive odd numbers starting from 1. 1 + 8 = 9 9 + 9 = 18 18 + 7 = 25 25 + 2 = 27 27 - 6 = 21 Following this pattern, the next number in the series would be 21 + 1 = 22.
21
24
24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.
To find the next number in the series, we can observe the alternating pattern between pairs of numbers. The first number is 14, and it decreases by 3 to 11, then increases by 7 to 18. Following this pattern, the next number after 18 should decrease by 2, resulting in 16. Therefore, the next number in the series is 16.
13 18 16 21 19 24 22 27 25 ... . This series consists of adding 5 to the first number and subtracting 2 from the next number, repeating the sequence in that order.
3 The series is obtained by subtracting a number that reduces by 1 at each stage 18 - 5 = 13 13 - 4 = 9 9 - 3 = 6 6 - 2 = 4 4 - 1 = 3
18
24 for each number you add 5 and then subtract 2. 19 plus 5 is 24.
The next number in the series 4, 12, 6, 12, 36, 18, 36
Since the numbers are going down be 5,4,3,2, the next number would be 3. It would be 3 because it would then go down by one.
The next number in the series 4-12-6-12-36-18-36.. is 108.
