FORMULA
a(n)=10n+r(n) where r(n) takes values in {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}.
EXAMPLE
G.f. = 19*x + 28*x^2 + 37*x^3 + 46*x^4 + 55*x^5 + 64*x^6 + 73*x^7 + 82*x^8 + ... - Michael Somos, Jun 09 2019
MATHEMATICA
a[ n_] := If[ n < 1, 0, 10 n + Mod[-Total@IntegerDigits[n], 10]]; (* Michael Somos, Jun 09 2019 *)
PROG
(PARI) isok(n) = !(sumdigits(n) % 10); \\ Michel Marcus, Dec 07 2013
(PARI) {a(n) = if( n<1, 0, 10*n + (-sumdigits(n))%10)}; /* Michael Somos, Jun 09 2019 */
(Haskell)
a094677 n = a094677_list !! (n-1)
a094677_list = filter ((== 0) . flip mod 10 . a007953) [1..]
