I know roughly what has to be done here, but for some reason its not working out like the other questions, any help would be greatly appreciated!
I think I see why that fraction has to be less than one. That right hand side should be k+1, or whenever you add the next term to the LHS you only add one to the RHS? So that fraction we gained from the LHS has to be less than 1 for the RHS to still be greater?
Thanks guys for your help!
