Can you prove that #1^2+2^2+3^2+..+n^2=1/6n(n+1)(2n+1)#?
Updated as of 5/1/2020 In the interest of health and public safety, JP 1-2 has suspended ALL JURY SERVICE until further notice. Per the Third Amended Order Regarding Court Proceedings Pending COVID-19 State of Emergency, all hearings and service are suspended until further notice. So I would send them a registered letter, return receipt requested, explaining that I am not paying the bill because (1) it was my understanding at the time that it was fully covered by the insurance, and that (2) my obligation was satisfied by the copay, and (3) if this was not the case the time to inform me was a year and a half ago.
