Altug Alkan, Table of n, a(n) for n = 1..20000

EXAMPLE

a(10) = 11 because A275945(10) = 11.

a(11) = 22 because A275945(11) = 13 and (13+31)/2 = 22.

a(12) = 33 because A275945(12) = 15 and (15+51)/2 = 33.

PROG

(PARI) A055642(n) = #Str(n);

A007953(n) = sumdigits(n);

a(n) = ((10^A055642(n)-1)/9)*(A007953(n)/A055642(n));

for(n=1, 1e3, if((((10^A055642(n)-1)/9)*A007953(n)) % A055642(n) == 0, print1(a(n), ", ")));
