1. The problem statement, all variables and given/known data actually got two questions but both are related so put them in the same place the question asks Determine whether the geometric series is convergent or divergent. If it is convergent, find its sum. Inf 1.) E 6(0.9)^(n-1) n=1 Inf (-3)^(n-1) 2.) E --------------- n=1 4^(n) the (E) is the sigma sign asking for sum the Inf is infinity and n = 1 is inital starting point they want us to evaluate the series sum from 1 to infinity 3. The attempt at a solution not really sure where to start. i can figure out the converging or diverging part just plug in some numbers and see if it is getting bigger (going to infinity) or if it leavels off. not sure how to find the sum. probaly just a simple formula but the Professor did not give it to us.
