Table of n, a(n) for n=1..76.

a(n) = (A070854(n)-1)/10^n. - Chandler

a(1) = 1 because A030430[1] = 11 is a smallest prime of form 10*k + 1.

a(2) = 1 because A062800[1] = 101 is a smallest prime of form 100*k + 1.

Cf. A030430, A062800, see A070854 for resulting primes.

Sequence in context: A226512 A270307 A261480 * A322934 A077629 A184467

Adjacent sequences: A121169 A121170 A121171 * A121173 A121174 A121175
