59 is the next number in this series.
This is the Fibonacci Series, where each term is the sum of the previous two. It continues 21, 34, 55 etc
I'm convinced that 3,840 is.
The series appears to increase as follows: 1 (+3), 4 (+5), 9 (+7), 16,, etc. If so, the next number in the series would be 25 (16 + 9). * * * * * While mathematically equivalent, a simpler description is: 12, 22, 32, 42, 52 ...
The next number is -21
the answer will be 21

225
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.

21.

A single number, such as 12848384 does not make a series.
The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.
12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50
Well, the pattern is the previous number plus the current number. So the next three numbers would be 21, 34, 55...
