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.
It looks like it is +6, -5, +12, -5. So I would assume the next number is +18, or 29.
243
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.
343.
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.
11 is added to each number in the question in turn, the next number will be 49
125 (the sequence is successive numbers cubed)
It looks like it is +6, -5, +12, -5. So I would assume the next number is +18, or 29.

60.75
the answer is 27
64. It's the sequence f(n) = n^3
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.
