    How can 2^n > n be proven by induction?

    "The idea is that you assume that your statement is true for n = k (the induction hypothesis), and then use that to show that the statement is also true for n = k + 1." Yes, I understand that this is the objective, but I am wondering if there is a general method of doing this and how you would...

    How can 2^n > n be proven by induction?

    Homework Statement prove 2^n > n by induction Homework Equations The Attempt at a Solution In my math class we start off assuming 2^n > n is true for n=k. Then we try to prove that when n=k+1 the inequality is true. So,I start off going, 2^(k+1) > (k+1) which is equivalent to...
