%N a(1)=1. a(n) = a(n-1) + (sum of the terms, from among terms a(1) through a(n-1), which are coprime to sum{k=1 to n-1} a(k)).
%e The sum of the first 6 terms of the sequence is 128. There are 4 terms from among the first 6 terms of the sequence that are coprime to 128 (a(1)=1, a(3)=5, a(4)=11, a(6)=79). So a(7)= a(6) + 1 + 5 + 11 + 79 = 175.
