f (n) = \frac{x - 6}{120} n^{5} - \frac{x - 6}{8} n^{4} + \frac{17 (x - 6)}{24} n^{3} - \frac{15 (x - 6)}{8} n^{2} + \frac{137 x - 762}{60} n + 6 - x

input n = 6 and the desired x

i . e .

x = 5 \Rightarrow f (n) = - \frac{n^{5}}{120} + \frac{n^{4}}{8} - \frac{17 n^{3}}{24} + \frac{15 n^{2}}{8} - \frac{77}{60} n + 1

x = 6 \Rightarrow f (n) = n

x = 7 \Rightarrow f (n) = \frac{n^{5}}{120} - \frac{n^{4}}{8} + \frac{17 n^{3}}{24} - \frac{15 n^{2}}{8} + \frac{197}{60} n - 1

\dots

we can find a polynome of degree 5 for any

x \in C, so {there}^{'} s no unique answer
