# Convergence Tests watch

1. Hello.

Does anyone know about convergence tests and if so could they check if my solutions are correct.

I can upload the questions and my solutions to them later.

Thanks

This is right. The last "series" should be "sequence" though.

ah thank you, apart from that though is everything fine. When I checked whether my answer was correct on wolfram they said something about a root test idk.

There's many ways to do it. Yours is probably the simplest. Root test is covered later and is more complicated.

Thank you morgan,

Wolfram says that it is a series though - are you sure it is a sequence. I am not sure myself.

Thanks for the help btw

It depends on what you are referring to. Let . Then is a sequence, but is a series.
In this case the sequence converges to 0.5 but the series does not converge.

The series is defined as the limit of the sequence of partial sums, . This could be what Wolfram is referring to as sequence.

Remember that a sequence is defined as a function from a subset of (often ). A series is just a number if it converges.

Thank you morgan.

Yes series is what I am most nearly referring to.
