The answer will depend on where, in the sequence, the missing number is meant to be. Also, in each case, there are infinitely many possible answers since it is possible to find a polynomial of degree 5 (or higher) that will go through each of the above numbers and ANY other number, missing from ANY position.
Using polynomials of order 4, though, there is only one answer for each position. For example,
First number missing: 171
Un= (-27n4+ 422n3- 2364n2+ 5611n - 4668)/6
Last number missing: 218
Un= (-27n4+ 314n3- 1260n2+ 2041n - 1026)/6

What is the missing number in 25 18 22 27 the average in 22?
The missing number is 18
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 pattern 1 8 27 blank 125 116?
I think your last number should be 216 as the others are the cubes of numbers 1, 2, 3 and 5. The missing number is 4 cubed, ie 64.
What number completes the pattern 16 4 12 36 9 27 44 11?
456445
What is the missing number in the list of numbers -43 23 -11 12 -27?
The answer depends on where, within the sequence, the missing number should have been.
