Programs

Floor[9/5 Range[0, 100]] + 32 (* Paolo Xausa, Jan 29 2024 *)

PARI

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

Formula

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

From Reinhard Zumkeller, May 03 2010: (Start)

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

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

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
