Consecutive odd numbers differ by 2.
n + (n + 2) + (n + 4) = 21
n + n + 2 + n + 4 = 21
5, 5+2=7, 5+4=9
Small thing (very small).
It's a slicker operation if you call them (n-2) , n, (n+2)
I mean, obviously it makes no difference, but I prefer it :D
Yes, the twos cancel.
Did you review my solution to your "fun" problem the other day?
Not the answer you are looking for? Search for more explanations.
no, sorry :( I'll try and find that thread again
A real shame :( You (I think) misread the fractions 1/3 1/5 1/7 etc as 13, 15, 17. I think that is the cause of the difference. I assume yours are correct to the (slightly different) problem though.
I will redo it with your fractions.
Thanks for responding.
I look forward to it
After my last post above, I remember taking a screen capture of the problems that you posted on this math site so that I would not make any errors in the equations to be solved. Refer to the attachment, a screen capture.
I will check the equations carefully again.
