Question

Can someone help me with these challenge problems? 1-7, 1-9, and 1-10. I have absolutely no idea how to do them. Thank you

Answer 1

i think 10 is the golden ratio

Answer 2

you can start by computing
\[\frac{1}{1+\frac{1}{1+1}}\]

Answer 3

or if you can prove that the limit exists, then you would know that
\[x-1=\frac{1}{x}\]

Answer 4

ok, but how can I do that?

Answer 5

you were right about 10, it is the golden ratio thanks
