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.
