A Closed-Form Evaluation of a Continued Fraction from the Ramanujan Machine

We provide a complete proof for a conjectured continued fraction identity catalogued by the Ramanujan Machine project. The continued fraction is defined by\(a_0 = 4,\; a_n = 3n^2+7n+4\;(n≥ 1),\; b_n = -2n^2(n+1)^2\;(n≥ 1),\)and we prove that its limit is exactly \(1/1-ln 2\). The proof establishes a closed form for the numerators \(P_n\), expresses the convergents via a telescoping sum, and evaluates the resulting infinite series using elementary integration. Convergence follows directly from the explicit expression of the convergents as partial sums of a convergent series.
