1,1

To shorthand the n-th - smallest n-digit prime it is convenient to distract the 10^(n-1) (n>1). Compare A107108(n) with A069100(n).

A107108(1)=2; at n>1 A107108(n)=prime(pi[10^(n-1)]+n)-10^(n-1)=A069100(n)-10^(n-1).

A069100={2, 13, 107, 1021, 10061, 100069, 1000117, 10000189, 100000193, 1000000181, 10000000259, 100000000193, 1000000000303, 10000000000411, 100000000000487, 1000000000000513, 10000000000000931, 100000000000000591}; A107108=Flatten[{2, Table[A069100[[i]]-10^(i-1), {i, 2, 18}]}]
