If the first and the 2n-1 th terms
WebFormula 1. Given an arithmetic sequence, we can calculathe the sum of its first n terms, which we write S n, using the formula : S n = n 2 ( u 1 + u n) Where u 1 is the first term … 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.
