 A134885 Triangular sequence from polynomials that gives roots near 137. 0
 1, 137, -1, -135, -137, 1, 134, 0, 137, -1, -133, 0, 0, -137, 1, 132, 0, 0, 0, 137, -1, -131, 0, 0, 0, 0, -137, 1, 130, 0, 0, 0, 0, 0, 137, -1 (list; table; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS Alternative Mathematica code for larger polynomials: p[x_, n_] = (-1)^(n - 1)*(135 - n) + (-1)^(n - 1)*137*x^(n - 1) - (-1)^ n - 1)*x^n Table[p[x, n], {n, 2, 10}] LINKS FORMULA p(x,0)=1 p(x,1)=137-x p(x,n)=(-1)^(n-1)*(135-n)+(-1)^(n-1)*137*x^(n-1)-(-1)^(n-1)*x^n: n>2 a(m,n) = CoefficientList(p(x,n),x) EXAMPLE p[x,134] gives: -1 - 137 x^133 + x^134 Triangular sequence: {1}, {137, -1}, {-135, -137, 1}, {134, 0, 137, -1}, {-133, 0, 0, -137, 1}, {132, 0, 0, 0, 137, -1}, {-131, 0, 0, 0, 0, -137, 1}, {130, 0, 0, 0, 0, 0, 137, -1} MATHEMATICA p[x_, n_] = (-1)^(n - 1)*(137 - n) + (-1)^(n - 1)*137*x^(n - 1) - (-1)^( n - 1)*x^n a = Join[{1, 137 - x}, Table[p[x, n], {n, 2, 10}]] c = Table[CoefficientList[a[[n]], x], {n, 1, Length[a]}] Flatten[c] CROSSREFS Sequence in context: A233254 A001330 A091510 * A259680 A082726 A189998 Adjacent sequences:  A134882 A134883 A134884 * A134886 A134887 A134888 KEYWORD uned,tabl,sign AUTHOR Roger L.
