Convergence of an=(1−12)(12−13)…(1n−1n+1)a_n=(1-\frac12)^{(\frac12-\frac13)^{…^{(\frac{1}{n}-\frac{1}{n+1})}}} [closed]

I’m interesting to see the opinion of MO about my question which I posted here in SE, Answers I received have not convinced me, And no clear proof posted there only numerical computation are provided. I should post the question as it is in order to know more about convergence of the titled sequence

Question:
let us moving to telescopic sum using exponent, Assume we have this sequence: an=(112)(1213)...(1n1n+1) with n1, this sequence can be written as power of sequences: xnyncn such that all them value are in (0,1), I want to know if the titled sequence should converge to 1? and how we can evaluate it for n go to ?
