is it necessary to factor "a" out ? we need the value of "r" to tell if it is a geometric series with r>1 or <1

How do you calculate the sum if both 'r' s are convergent?

I don't understand why you conclude that the series is divergent while we have both convergence and divergent.

Why ddnt he find the sum or maybe it is bcs the series diverges?
