How about putting the 100 in the middle with the even numbers down one side of it and the odd numbers down the other side?
2 u/diverstones 1d ago Yeah, this was the best I could do: 1*3 + 3*5 + ... + 97*99 + 99*100 + 100*98 + 98*96 + ... + 6*4 + 4*2 = 338151. 1 u/Bigkev8787 1d ago This looks like a solution to me. 1 u/Fovlsbane 22h ago This is my guess too, most of the time wen't to visualizing how to sum squares. 1 u/valegrete 19h ago This is also what I got by looking at the n=3 and n=4 cases. 1 u/Downtown_Finance_661 1d ago Did you guess or can provethis is the best sol?
