Which convergence test would you use to determine whether this series, converges.

How do you know which one to use. And could you show me how this particlular example works please???????!!!!!!!!!

Sometimes maths is a pain.

For n > 10, we have e^(-n) < 1/6.

Thus for sufficiently large n.

Is that using any test im not aware of, or is that just by deduction?

It's the comparison test (also known as direct comparison test).
