270.
The sequence could be
t(n) = 11.5n3 - 75n2 - 159.5n - 90 (for n = 1, 2, 3, ...)

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.
The pattern is +2 /2 +3 /3 +4 /4, and the next term would be +5, or 8.
The next number in the sequence is 48.

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.
8 and then 1.6
If the last number is 1/3 (it should be), the next number is 5 and 1/3
21
The next is 3.
39. The rule here is starting with the number 9, add (-6 + sequence number * 6). 9 + (-6) = 3 3 + 0 = 3 3 + 6 = 9 9 + 12 = 21 21 + 18 = 39 39 + 24 = 63
To find the next number in the sequence 18, 24, 31, 24, 30, we can observe the pattern. The sequence alternates between increasing and then decreasing or stabilizing. The differences are +6, +7, -7, +6. Following this pattern, the next logical difference after +6 would be -7, which means we would subtract 7 from the last number, 30. Therefore, the next number in the sequence would be 30 - 7 = 23.
To identify the next number in the sequence 40, 42, 21, 24, 8, 12, 3, we can observe a pattern in the pairs: 40 to 42 (add 2) 42 to 21 (divide by 2) 21 to 24 (add 3) 24 to 8 (divide by 3) 8 to 12 (add 4) 12 to 3 (divide by 4) Following this pattern, the next operation should be to add 5 to 3, resulting in 8. Thus, the next number is 8.

The pattern is +2 /2 +3 /3 +4 /4, and the next term would be +5, or 8.
