The number 9 [3] is absent from the series 27, 54, 86, __, 187, and 272. The sum of three consecutive even integers (72) and the product of those three integers (13728) can be used to find this number, which is a component of a sequence that includes every other positive, odd integer [3].
So, here what is missing is we gonna find by doing basic arithmetics. hence, The missing number in the series 27, 54, 86, __, 187, 272 is 128. The pattern is +27, +32, +32, +101, +85.
