Convergent Series

\textrm{This demo shows the terms of a sequence } a_n \textrm{ along with the sequence of partial sums } s_n = \sum_{j=1}^n a_j. \\ \textrm{The value of the term and the sum at index N will be displayed. } \\ \textrm{Check the box labelled "sums" to display the sum of the series, if it is convergent.}
