The sum in sigma notation for the sequence will be as follows:
From
5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50
first term=5
common difference=5
number of terms=10
n=nth term
thus the sum will be:
(i=2 to 10)∑(5(n-1)+5)

how do I cancel this out??? this is the only thing I don't understand... have an a on my class but... never get these right...

You factor the expression first leaving you with $\frac{3xy(z-1)}{3xy}$
Then you would cancel out 3xy as because there is exactly one on each side. This, in turn, would leave you with z - 1
