So far all I have been able to do is show p (5) holds and assume P (k) which gives the form 2^ (K)&gt;k^2. This is where I am stuck; consequently, I don't know how to show p (k) implies ... WebYou would solve for k=1 first. So on the left side use only the (2n-1) part and substitute 1 for n. On the right side, plug in 1. They should both equal 1. Then assume that k is part of the sequence. And replace the n with k. Then solve for k+1. k+1: 1+3+5+...+ (2k-1)+ (2k+1)=k^2+2k+1 The right hand side simplifies to (k+1)^2 2 comments ( 20 votes)
