121.
25 is the next number that appears in that sequence.
243
It is obvious that 7 is added to get the next number from the previous one.
Each is half of the previous number, so 6.25 will be next.
35
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.
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
the next number in the sequence 1 5 25 125 is 625
The next number in the sequence would be 25.
25
The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.
This is a geometric sequence. Each number is multiplied by the same constant, to get the next number. If you divide any number by the previous one, you can find out what this constant is.
