This appears to be two interwoven sequences.
The first sequence, increases by 9 then 19......7 + 9 =
16........8 + 19 =
27
The second sequence decreases by 8 then 18....16 - 8 =
8........27 - 9 =
18
The next number would thus be 9 + 29
=
38.
The next number in the sequence is 27.
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.

The next number in the sequence is 27. To get the next number, double the number and add one. Except for the second number, all the numbers in the sequence follow this rule.
It is: 34
The next number in the sequence is 27.
The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.
The next number in this sequence should be 33.
125 (the sequence is successive numbers cubed)
The pattern alternates between adding a sequence of numbers and a constant. Starting with 7, adding 9 gives 16, then subtracting 8 gives 8, adding 19 gives 27, and subtracting 18 gives 9. Following this pattern, the next number would be 9 + 29, which equals 38. Thus, the next number in the sequence is 38.
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.

the answer is 27
64. It's the sequence f(n) = n^3
