The answer depends on which number is missing. Even if the location of the gap is know, there are infinitely many possible solutions. The solutions listed below are polynomials of the lowest degree.
First:
5 using the rule Un = (-4n3 + 48n2 - 128n + 99)/3
Second:
0 using the rule Un = (-7n3 + 84n2 - 209n + 138)/6
Third:
21.666 (recurring) using the rule Un = (3n3 - 23n2 + 84n - 61)/3
Fourth:
50 using the rule Un = (-11n3 + 90n2 - 121n + 48)/6
Fifth:
65 using the rule Un = (-4n3 + 36n2 - 44n + 15)/3

What is the missing number in the sequence 1-8-27--125-216?
64 It is a series of cubes 13, 23, 33, 43, 53 etc
What is the missing number 33 something 24 27?
The sequence appears to be decreasing by 3, then increasing by 3. Following this pattern, starting from 33, if we subtract 3, we get 30. Thus, the missing number is 30. The complete sequence would be 33, 30, 24, 27.
What is the missing number in the sequence 1-8-27-125-216 is it 36 or 45 or 93 or 64?
64 because the series is 13, 23, 33, 43, 53, 63
What is this number sequence 35 33 29 23 15 7?
The sequence interval is 2 4 6 8 ( this is the difference of number). so the missing number is -1 if I'm not mistaken.
Is this an arithmetic sequence or a geometric sequence 13 23 33 43 53?
Arithmetic- the number increases by 10 every term.

What is the missing number in the sequence 1 9 28 - 126 217?
65.......but there is a slight problem. The sequence appears to be a(n) = n3 + 1 apart from the first term which should be 2 as 13 + 1 = 2 1 23 + 1 = 9 33 + 1 = 28 43 + 1 = 65.....the missing number 53 + 1 = 126 63 + 1 = 217
Find the missing number in the sequence 1 8 16 17 24 25 32 33?
9 (between 8 and 16).
What is the next number in this number sequence 1 8 27 64?
13 ...23 ...33 ...43 ...53=125■
What is the pattern of the number sequence 1 8 27 64 and 125?
They are perfect cubes: 13, 23, 33, 43, and 53.
What is the next number 50 33 25 20 17 14 13 11?
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.
What is the 10th term for the sequence 6 18 11 33 26 78 213 206?
There seems to be a number missing between 78 and 213. Please check and resubmit.
What is the logic behind the number sequence 1 - 8 - 27 - 64 - 125 - 216?
