 OFFSET 0,2 COMMENTS Eleventh column (m=10) of triangle A112707 (partial sums of Catalan numbers multiplied by powers of nonpositive numbers). LINKS FORMULA a(n)= A112707(n+10, 10), n>=0. G.f.: c(-10*x)/(1-x), where c(x):=(1-sqrt(1-4*x))/(2*x) is the o.g.f. of Catalan numbers A000108. G.f. for unsigned sequence: c(10*x)/(1+x), hence |a(n)| is the convolution of the sequences {C(n)*10^n} and {(-1)^n}, where C(n):=A000108(n). CROSSREFS Cf. A113268 (m=9). Sequence in context: A157387 A218422 A119291 * A307387 A332119 A261826 Adjacent sequences:  A113266 A113267 A113268 * A113270 A113271 A113272 KEYWORD sign,easy AUTHOR Wolfdieter Lang, Oct 31 2005 STATUS approved
