How do you determine if #Sigma (7^n-6^n)/5^n# from #n=[0,oo)# converge and find the sums when they exist?
See below.
Concluding this is a divergent series.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
