Question: What is the formula for the sum of an arithmetic series? this is the sequence i am working with\n\n2,4,6,8,10

Answer: Fortunately, there is a simple formula for finding the sum of an Arithmetic Series. \n\nIn general, the sum of an Arithmetic Series can be written as follows: \n\nS = i + (i+d) + (i+2d) + (i+3d) + ... +[i+(n-1)d]\n\nand can be simplified as: \n\nS = (n / 2) * [2i + (n-1) * d] \n\nwhere\ni is the initial term,\nd is the difference between successive terms and\nn is the number of terms in the series.
