Your sequence seems to be a cubed sequence, but you are missing 64 between 27 and 125.
13 = 1
23 = 8
33 = 27
43 = 64
53 = 125
63 = 216
So, next would be 73, which equals 343.
The next number in the sequence is 480
The next number could be 26 The next number could be 12 - - - - - - - - - The next number that is in the sequence is 12.
381838 is one number: it does not describe a sequence.
One number is not sufficient to identify a sequence.
To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96
A single number, such as 171422, does not constitute a sequence.
A single number, such as 122.4832 does not constitute a sequence.
A single number, such as 2726101400, does not make a sequence.
The next number in the sequence will be 56.
Without a sequence given in the question, the next number to 6 is 7.
The nest number in the sequence is 18. Note that the difference between each number and the next number in the sequence follows the simple sequence of 1,2,3,4. Obviously the next in the sequence of increases is 5, so 13+5=18.
