Hello! I need to insert 91 numbers and use the sum function in a formula to sum them.
This is the formula I need to make:

Could you please tell me how can I accomplish this? How do I make an "i" index and how do I define "n"?
I am a complete novice in using Smath, this is for a university coursework.
Thank you very much!
