Prove by mathematical induction that

n

r = 1

so far I have

1

r=1

1 = 1(4)/2

1 = 4/2

1 = 2

I'm not sure what to do after this for the k+1 case.

n

*sigma*r^3 = n^2(n+1)^2/4r = 1

so far I have

1

*sigma*r^3 = 1^2(1+1)^2/2r=1

1 = 1(4)/2

1 = 4/2

1 = 2

I'm not sure what to do after this for the k+1 case.
