Default Urgent, Help

Alright, I have homework I need finished by tommorrow. Here is a problem or two.
7. Expressed in terms of n what is the sum of all the terms in the arithmetic sequence (n-7), (n-2), . . . . (n+428)?
8. If x = a/b, find (a+b)/(a-b) in terms of x.
Inception can go beyond just a dream.
