WebTo find the next few terms in an arithmetic sequence, you first need to find the common difference, the constant amount of change between numbers in an arithmetic sequence. Once you know the common difference, you can use it to find those next terms! This tutorial takes you through that process, so be sure to check it out! WebIf you put n=1 into the S (n) formula, you get that the sum of the first 1 terms = 2/11. Now if you look at his a (n) formula that he works out and put n=1 into it, it does not equal 2/11. It equals 9/110 So the sum of the first 1 terms is 2/11, but the first term is not 2/11. Is there something I don't understand? Thanks in advance.
