%H Ray Chandler, <a href="/A085259/b085259.txt">Table of n, a(n) for n = 0..1000</a>

%H <a href="/index/Rec#order_06">Index entries for linear recurrences with constant coefficients</a>, signature (1,0,0,0,1,-1).

%F a(n) = floor(9*n/5+32).

%F From _Reinhard Zumkeller_, May 03 2010: (Start)

%F (a(n) + A177154(n)/10 - 32)*5/9 = n;

%F a(n) = A029925(n) - floor(A177154(n)/5). (End)

%F G.f.: -(30*x^5-2*x^4-2*x^3-2*x^2-x-32) / ((x-1)^2*(x^4+x^3+x^2+x+1)). - _Colin Barker_, Mar 23 2013

%e a(5) = 41 (exactly), a(-40) = -40 (also exactly).

%t Floor[9/5 Range[0, 100]] + 32 (* _Paolo Xausa_, Jan 29 2024 *)

%o (PARI) f(n) = for(c=0,n,print1(floor(9/5*c+32),","))

%Y Cf. A029925, A029926, A085268, A177154.
