I really don't get this. Can someone please help me?(adsbygoogle = window.adsbygoogle || []).push({});

Apply the proof of the Cantor-Schroder-Berstein theorem to this situatuion:

A={2,3,4,5,...}, B={1/2,1/3,1/4,...}, F:A-->B where F(x)=1/(x+6)and G:B-->A where G(x)=(1/x)+5. Note that 1/3 and 1/4 are in B-Rng(F). Let f be the string that begins at 1/3, and let g be the string that begins at 1/4.

a)Find f(1), f(2), f(3), f(4).

For this one, f(1)=1/3, then f(2)=1/(1/3)+5=8, then f(3)=1/(8+6)=1/14, and f(4)=1/(1/14)+5=19? Is that right? and then I do the same for g? g(1)=1/4, g(2)=9, g(3)=1/15, and g(4)=20?

b) Define H as in the proof of the Cantor-Schroder-Berstein theorem and find H(2), H(8), H(13), and H(20).

I have no clue how to do this one at all. Can you help me please?

Thanks for the help!
