Write proof

You can write formulas in LaTeX or in plain text, and write your solution in any language.

Let n≥2n\ge2n≥2 be an integer and let x1<x2<⋯<xnx_1<x_2<\cdots<x_nx1​<x2​<⋯<xn​ be real numbers satisfying

∏1≤j≤nj≠i∣xi−xj∣=xi2+1for every 1≤i≤n.\prod_{\substack{1\le j\le n\\j\ne i}}|x_i-x_j|=x_i^2+1 \qquad\text{for every }1\le i\le n.1≤j≤nj=i​∏​∣xi​−xj​∣=xi2​+1for every 1≤i≤n.

Determine all possible values of nnn and all corresponding tuples (x1,x2,…,xn)(x_1,x_2,\ldots,x_n)(x1​,x2​,…,xn​).
