The next perfect number after 11 is 28.
To find the next number in the sequence 4, 11, 25, 53, we can observe the differences between consecutive terms: 11 - 4 = 7, 25 - 11 = 14, and 53 - 25 = 28. The differences (7, 14, 28) double each time, suggesting the next difference should be 56. Adding this to the last number, 53 + 56, we get 109 as the next number in the sequence.
The next whole number is 12.
