Let  $n$  be a positive integer. Find the largest real number  $\lambda$  such that for all positive real numbers  $x_1,x_2,\cdots,x_{2n}$  satisfying the inequality
\[\frac{1}{2n}\sum_{i=1}^{2n}(x_i+2)^n\geq \prod_{i=1}^{2n} x_i,\]
the following inequality also holds
\[\frac{1}{2n}\sum_{i=1}^{2n}(x_i+1)^n\geq \lambda\prod_{i=1}^{2n} x_i.\]
