Let's show the convergence using the ratio test. (it's often useful when the terms of the series are defined by fractions or products)
Simplifying what's in red and using and :
The series converges if .
Hope that helps.
determine convergence and show all work
Sigma [3*5*7...(2n+1)] / [18^n(2n-1)n!]
I have been trying to do this problem for several days I have managed to figure out all the others but this one has me stumped.
Thank Your for your time
