This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
If you mean: 1 4 9 16 25 then it is 36
The next square number after 16 is 25
The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
25 is the next number that appears in that sequence.
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.
25
The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.
If you mean: 1 4 9 16 25 then it is 36
It is: 6 squared = 36
10 30 15 16 48 24 25 75...
The next square number after 16 is 25
The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
25 is the next number that appears in that sequence.
you add the next odd number in the sequence. first you add 1, then 3, 5, 7, 9...
75. The sequence is:- multiply by three, divide by two, add one.
121.
