Hi Tony123;

   What are you asking for? Are you asking for what value of n that would make that sum equal 400, because I don't think that is possible.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
