next questiooooon!


can i get a sigma formula where the first three terms in the infinite series are 2.2,2.42,2.662


it is similar to pascals triangle, if that helps

The common ratio between terms is  1.1


If we are just trying to find the  nth term, we can use


an  =  (2.2)(1.1)^(n - 1)


If you are summing these terms we have...



2.2 * ∑  (1.1)^(n - 1)  




cool cool cool
