We give an elementary proof that any natural number can be written as
the sum of three terms of the
sequence ⌊ n2/3 ⌋n ∈ N .
This is a recent conjecture of the author that
was very recently confirmed by Mezroui et al.; they used a result
due to Bateman and derived from the theory of modular forms. We also
state some conjectures related to the subject.
