To find the next number in the sequence 5, 15, 12, 24, 21, 21, 18, we can analyze the pattern. The differences between the numbers are: 10, -3, 12, -3, 0, -3. Following this pattern, the next difference would likely be 12, resulting in a next number of 18 + 12 = 30. Thus, the next number in the sequence is 30.
..... 27, 24, 26, 25, 25, 26, 24, 27, 23 .....A number is decreasing by 1 while another number is increasing by 1
651 is the next number.
30!

24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.

24 for each number you add 5 and then subtract 2. 19 plus 5 is 24.
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.
21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33
