Error in the 3rd formula?


#1

Hi,

Is there an error in the 3rd formula?
Shouldn’t the summation be “=1+4+9+⋯+i^2” instead of “i^n”?

Hi Dennis,

Thank you for reaching out! We are happy to hear from you.

It should actually have been n^2, and we’ve fixed it. Thanks for pointing this out :slight_smile:

If you have any further queries, please let us know.
