In all articles found the formula for the square pyramidal number is proofed by using the inductive methode. Isn't there a direct proof?

:I thought inductive was direct. An empirical proof (e.g., having a computer calculate the first thousand values using each formula and then having it compare that the lists are all the same) would convince more people, but symbological snobs would look down on it.
