Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Floor of sum of the first 10^n square roots.
%e The first 10^0 square roots is 1. The sum of the first 10^1 square roots is 22.468278186... . So 22 is the second entry in the sequence.
