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.
Each is half of the previous number, so 6.25 will be next.
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
183 + 1 = 44 + 2 = 66 + 3 = 99 + 4 = 13Etc. The next number in the sequence would be 18, then 25, and so on.Ans 2.The previous answer contains an error.The next number in the sequence would be 18 (13 + 5),after which comes 24 (18 + 6 ) not 25.

25 is the next number that appears in that sequence.
The sequence appears to be decreasing with varying intervals: 50 to 33 (17), 33 to 25 (8), 25 to 20 (5), 20 to 17 (3), 17 to 14 (3), 14 to 13 (1), and 13 to 11 (2). The differences between the numbers suggest that the next number decreases by 1 from 11, resulting in 10. Therefore, the next number in the sequence is 10.
121.

The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
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.
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.
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.
