Any number that you choose can be the next number. It is easy to find a rule based on a polynomial of order 5 such that the first five numbers are as listed in the question followed by the chosen next number. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.
In this case the simplest solution, based on a polynomial of order 4 is
t(n) = (-77*n^4 + 874*n^3 - 3400*n^2 + 5321*n - 2676)/6 for n = 1, 2, 3, ... and accordingly, the next number is 693.

Which number comes next in this seriesWhich number comes next in this series 18 81 27 72 36 63?
The series alternates between two patterns: one where numbers are multiplied by 3 and then reduced (18 to 27 to 36) and another where numbers are multiplied by 4 and then reduced (81 to 72 to 63). Following this pattern, the next number after 36 (from the first sequence) would be 45 (36 multiplied by 1.25), and after 63 (from the second sequence), the next number would be 54 (63 reduced by 9). Thus, the next number in the series is 45.
What is the next number 7 21 8 72 9?
The sequence alternates between multiplying a number and then adding one. Starting with 7, multiplying by 3 gives 21, then adding 1 gives 8. Next, multiplying 8 by 9 gives 72, and adding 1 gives 9. Following this pattern, the next step would be to multiply 9 by 11, resulting in 99. Thus, the next number is 99.
