Proof by squarisation:
 _ _ _ _ _             _       _ _ _ _ _ _
|_|_|_|_|_|          _|_|     |_|_|_|_|_|_|
|_|_|_|_|          _|_|_|     |_|_|_|_|_|_|
|_|_|_|     +    _|_|_|_|  =  |_|_|_|_|_|_|  =  5 x 6

 5+4+3+2+1  +  1+2+3+4+5   =   5+5+5+5+5+5   =  30

Replace 5 by n, for large values of 5. :-)
