Robert Israel, Table of n, a(n) for n = 0..1000
FORMULA
a(n) = 2/3*n^(3/2) + 1/2*n^(1/2) + O(1). It appears that the absolute value of the difference is always less than 1. - Robert Israel, May 06 2019
MAPLE
map(ceil, ListTools:-PartialSums([seq((sqrt(k)), k=0..100)])); # Robert Israel, May 06 2019
