(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A035334 a(n) = smallest number which is not the sum of exactly 1 or a(n-1) earlier terms. 1

%I

%S 1,2,5,3,14,4,39,6,119,7,352,8,706,9,2104,10,4209,11,8419,12,24552,13,

%T 49106,15,188594,16

%N a(n) = smallest number which is not the sum of exactly 1 or a(n-1) earlier terms.

%e a(5)=14 since all earlier numbers are either in list (1,2,3,5) or the sum of 3 terms from list (4=1+1+2, 6=2+2+2, ..., 12=2+5+5, 13=3+5+5).

%Y Cf. A055456.

%K nonn
