The sequence appears to be increasing by a certain amount each time. The differences between the numbers are 6, 7, and 8, respectively. This suggests that the next number in the sequence should be 22 + 9, which equals 31.

74 add 13 each time
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
The numbers are increasing by increments of 13 and so the next number is 61+13=74
