The sum of the first \(n\) terms of an arithmetic sequence is given by \(S_n = \frac{n}{2}(2a + (n-1)d)\). If the first term \(a = 5\), the common difference \(d = 3\), and \(S_n = 155\), find \(n\).! đź’Ą View latest background details and public records for The Sum Of The First \(N\) Terms Of An Arithmetic Sequence Is Given By \(S_N = \Frac{N}{2}(2A + (N-1)D)\).
