Best ResponseYou've already chosen the best response.2Here it goes. \[S_{n} = \frac{n}{2} [2a + (n1)d]\] a = first term, d=common difference , n=number of terms

Best ResponseYou've already chosen the best response.2Sorry for my silly mistakes :( I suppose the first one I wrote was for \(a_n\). but still, it's wrong! \(a_n=a_1+(n1)d\)
