8 and then 1.6
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.
It is: 34
My guess: 2.5
The next two numbers in the sequence are... 45 & 54.
21
22
The pattern in the sequence 3, 6, 12, 21 can be identified by examining the differences between consecutive terms: 6-3=3, 12-6=6, and 21-12=9. The differences (3, 6, 9) are increasing by 3 each time. Continuing this pattern, the next difference would be 12 (9 + 3). Therefore, the next number in the sequence is 21 + 12, which equals 33.
The next number in the sequence 3-15-6-30-21 is -207.
50. Fit the quadratic Un = 6.5n2 - 16.5n + 12
If the last number is 1/3 (it should be), the next number is 5 and 1/3
