This is the series of square numbers, (16= 4*4). The next number is 5*5=25.
33
The Pattern is 1^2- 2^2- 3^2- 4^2- 5^2 or 1 - 4 - 9 - 16 - 25 The next number in the series is 6^2 or 36
49 (it is an arithmetic series that adds 5 then 7 then 9 then 11 then 13)
The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.

The next square number after 16 is 25
16+6=22 22+3=25 25+0=25 Answer = 25 ps. forget about the 2nd, 4th, 6th number, they don't matter.
The Pattern is 1^2- 2^2- 3^2- 4^2- 5^2 or 1 - 4 - 9 - 16 - 25 The next number in the series is 6^2 or 36
The next number in the series will be 66. The next number is found by adding the two previous numbers. (2+7=9, 9+7=16, etc...)
25
49 (it is an arithmetic series that adds 5 then 7 then 9 then 11 then 13)
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 is 25 but there are the sequence is infinite so there can be no end to the sequence.
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 ...
These are squares. 12 = 1 22 = 4 32 = 9 (it is missing 42 = 16) 52 = 25 62 = 36 The next one in the series is probably 72 = 49.
