What if it starts with 405 and ends with 7?

[cluezieys]

I was left more confused after this video😅 appreciate the vid though

[DENNIEKLAhhneey]

Okay so where did you get that random 7? I'M SO CONFUSED pls

[lisakhanya_x]

Doesn't 7 supposed to be negative?

[shelliebelle]

Can you simplify the bottom equation and just simply leave it at that?

[samvelk.]

May we write on the bottom of sigma charachter i=7 top - n=405 and on right - i+2 ?

[angeliekylenunez]

thank youuuu dhjsccjscs, my problem is now solved

[jasonstewart]

Shouldn't that be 200? There's 200 integers...
