Homework Help?
Solve for n:

L= a + (n-1)d

Answer 1

L= a + (n-1)d subtract a
L-a=(n-1)d divide by d
(L-a)/d=n-1 add 1
1+(L-a)/d=n
n=1+(L-a)/d

Answer 2

L-a=(n-1)d
(L-a)/d=n-1
(L-a)/d+1=n

Answer 3

L-a=(n-1)d
(L-a)/d=(n-1)
n=(L-a)/d+1

Answer 4

Homework is a anguish within the ***, however it is valued at it and the penalties of no longer doing it are low grades, low self-worth, hating college, irritated father and mother, and awkwardness round academics. The first-class factor to do is simply DO the homework. Don't attempt to believe, "I can not..." or doubt your self - do just it!

Answer 5

First, distribute:

L = a + nd - d

now isolate:

L - a + d = nd

now separate:

n = (L - a + d) / d
or
n = (L - a)/d + 1
