Re: Summation

Yes, that is probably the only way. Practice!

Re: Summation

Hi soha;

Look at A) and B) of post # 47 you can see that each term has an n and an (n+1). You look for a common factor in each term. That is all there is to it. But as I said A) is perfectly acceptable in the real world. B) is considered more simple.
