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)
