The corresponding numerators are given in A294516. See this for a reference, the definition of V(4,3;n), and the limit V(4,3).
FORMULA
a(n) = denominator(V(4,3;n)) with V(4,3;n) = Sum_{k=0..n} 1/((k + 1)*(4*k + 3)) = Sum_{k=0..n} 1/A033991(k+1) = Sum_{k=0..n} (4/(4*k + 3) - 1/(k+1)).
EXAMPLE
For the rationals V(4,3;n) and the limit V(4,3) see A294516.
