In order for an infinite geometric series to have a sum the common ratio r must be between 1 and 1. S n a 1 r. It would be a geometric sequence and could be recursively defined as AnAn-134 where A1 14.
The formula for the n -th partial sum Sn of a geometric series with common ratio r is given by. Given the value of a First term of AP n Number of terms d Common Difference b First term of GP r Common ratio of GP. In mathematics geometric series and geometric sequences are typically denoted just by their general term aâ‚™ so the geometric series formula would look like this.
