Re: Maths Question Driving Me Insane
firstly that question is wrong, n^2 != n (but we'll ignore that unless you want to but some cheecky remarks in your book, the only time n^2 = 1 is when n=1).
the sequence is 1+3+5... + k-2 + k = n^2
n = k/2+.5
eg, 1 = 1^2 -> 1 = 1/2 + .5 = 1 (correct)
1+3 = 2^2 -> 3/2 + .5 = 2 (correct)
1+3+5 = 3^2 -> 5/2 + .5 = 3 (correct)
1+2+3+...+1999 = 1999 / 2 + .5 = 500,
n=500 and n^2 = 250,000
dammit, beaten to it, thats what happens when you answer the phone and have to explain how to share email folders!!!
actually not beaten to it,
like I said, the question is badly written, either me or stacy are squaring the wrong number
this comes frmo the way it's written, n=n^2

Im sick of people saying 'dont waste paper'. If trees wanted to live, they'd all carry guns.
