Test each of the given geometric series for convergence or divergence. Find the sum of each series that is convergent. $$10+9+8.1+7.29+6.561+\cdots$$
Added by Johnny F.
Step 1
To do this, we check if each term is a constant multiple of the previous term. We can see that each term is obtained by multiplying the previous term by 0.9. Therefore, the series is geometric. Show more…
