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

If the first number is 15 and then their was a space and then 21 what is the missing number?
If a progression goes 15 __ 21, then the missing number will dictate how the pattern increases with every number. If the missing number is 18, this means that the numbers go up in threes. The pattern would continue 24, 27, 30, 33...
