# Math Help - problem| calculating the limit of sequences

1. ## problem| calculating the limit of sequences

Hi

I have a problem with this excercise:

a>b>0
And I need to prove that An and Bn converge, and to calculate their limit.

Now, I proved that they converge, and that their limits are equal, but I can't find their limit..

Any ideas?

Show that: $a>a_1>a_2>\cdots>a_n>b_n>b_{n-1}>\cdots>\>b_1>b$

3. I already did this, it just helps to prove that the sequences converge, and that their limit is the same, but it's not helping for finding out the limit.
