%N A113264 Partial sums of Catalan numbers A000108 multiplied by powers of -5.
%C A113264 Sixth column (m=5) of triangle A112707 (partial sums of Catalan numbers multiplied by powers of nonpositive numbers).
%F A113264 a(n)= A112707(n+5, 5), n>=0.
%F A113264 G.f.: c(-5*x)/(1-x), where c(x):=(1-sqrt(1-4*x))/(2*x) is the o.g.f. of Catalan numbers A000108.
%F A113264 G.f. for unsigned sequence: c(5*x)/(1+x), hence |a(n)| is the convolution of the sequences {C(n)*5^n} and {(-1)^n}, where C(n):=A000108(n).
%Y A113264 Cf. A112711 (m=4).
