Hey all

Having an issue with a proof by induction. Here is the question:

n^{3}>2n+1

I got through the basis step, induction hypothesis step, but really struggled with understanding how to prove it. Have looked around at similar answers, but I believe I am just missing the key part of knowing what to do.

(k+1)^{3}>2(k+1)+1 - this is as far as I got.

Any help would be greatly appreciated!
