Okay, I attempted 3 of these and I don't know how to do the other two. So I hope I can get you guys to check if I am on the right track and teach me how to do the other two. Thanks a lot, a lot, a lot!

Use the airthmetic of limits, standard limits (clearly stated) or appropriate rules (clearly stated) to compute the limit of each sequence

if it exists. Otherwise explain why the sequence diverges.

(a)

=

I divided the whole thing with

and using standard limits I got,

Then I used l'Hopital's rule to solve the limit for the

and got 1/2 and just substituted it back in and my answer is 11/4.

(b)

I don't know how to do this one!

(c)

This one is to use sandwich rule right?

(d)

Used continuity rule and got,

divided the whole thing by n

= 0.5

(e)

I don't know how to do this one either.
