I am sorry to belabor the point, but is there anyway to reduce (2n-1)!/n! to a more simpler form--like the 1st commentator did? is what they did correct? i think that n! can be written as (1x2x(n-1)x(n-2)x...x(n)) but could that cancel with anything from the numerator? thanks

Thank you very much for the reply. When you write it out like that I can see that the product will eventually reach infinity. But how did you know to rewrite the expression as (2n-1)!/n! and what does a double factorial mean? thanks

Thank you for your reply but I have not had much experience with factorials. Could you please fill in the steps to reach how you got to that final expression? Also, could you please help me understand how to get a finite limit from a factorial? thanks
