The series is decreasing by consecutive perfect squares starting from 16^2 (256) and decreasing by 2^2 each time. Therefore, the next number in the series would be 4^2, which is 16.
24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.
This is the series of square numbers, (16= 4*4). The next number is 5*5=25.

The series is decreasing by consecutive perfect squares starting from 16^2 (256) and decreasing by 2^2 each time. Therefore, the next number in the series would be 4^2, which is 16.
16*3 = 48
It is: 16 squared = 256
22
Add successive square numbers. The next number is 57.
