%N Values of Newton-Gregory forward interpolating polynomial (1/3)*(2*n-7)*(2*n^2-11*n+18).

%H <a href="/index/Rec#order_04">Index entries for linear recurrences with constant coefficients</a>, signature (4,-6,4,-1).

%F a(n) - A177342(n-3) = (n-3)^2, with n>3. For n = 8, a(8) - A177342(5) = 174 - 149 = 5^2. [From _Bruno Berselli_, May 23 2010]

%F G.f.: ( -42+153*x-196*x^2+93*x^3 ) / (x-1)^4 . - _R. J. Mathar_, May 18 2014

%Y Equals A030441 shifted right twice.

%Y Cf. A177342 [From _Bruno Berselli_, May 23 2010]
