Hi

My name is Mr William, I am a student The question is secondary

I am trying to prove a induction question

Sigam r=1 n (2r -1)cube = n square (2 n square - 1)

Thanks.

The expression you have

is certainly true when n = 1.

Suppose now that the expression is true for n = k - 1, then for n = k,

You should now be able to complete the problem.

Cheers,
Harley
