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

a_{n} = (2.2)(1.1)^(n - 1)

If you are summing these terms we have...

inf

2.2 * ∑ (1.1)^(n - 1)

n=1
