Table of n, a(n) for n=1..65.

a(n) = A059921(n) + 1, n>=2.

a(5)=7 because 5^(6/5) ~ 6.8986; a(6)=9 because 6^(7/6) ~ 8.088.

Table[Ceiling[n^(1 + 1 / n)], {n, 100}] (* Vincenzo Librandi, Feb 18 2016 *)

(MAGMA) [Ceiling(n^(1+1/n)): n in [1..70]]; // Vincenzo Librandi, Feb 18 2016

Cf. A059921 (floor(n^(1+1/n))), A269023 (complementary sequence).

Sequence in context: A323828 A079581 A229858 * A057716 A138591 A136492
