Given any 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 and the sixth is the given number. That is, it is easy to find a rule so that any number can be the "next" in the sequence.
However, the simplest polynomial of order 4 is:
Un = (5n4 - 54n3 + 217n2 - 312n + 240)/12 for n = 1, 2, 3, ...
and, accordingly, U6 = 83.

What is the next number in the series 20-23-28-14-17-22-11?
The series is a sequence of three numbers, the second number is 3 greater than the first, and the third number is 5 greater than the second. (or 8 greater than the first) 20 + 3 = 23 : 23 + 5 = 28 14 + 3 = 17 : 17 + 5 = 22 11 + 3 = 14........is therefore the next number in the sequence.
What number comes next in this number series 2 3 5 7 11 13?
the numbers are only dividable by 1 or themselves, the so called, 'prime numbers', so the next one would be 17.
