Set this equation equal to zero. Then, set each factor equal to zero, and solve for x
7x+7=0
x^2+5=0

x=-1
x=+ or - √-5

For this second answer, simplify this to + or - i√5.
Note that if you were to distribute this, the highest exponent would be 3. This tells you how many answers there will be:
-1
i√5
-i√5

x=infinity
the equation would be y=70

deposit pluss
you have to pay an initial one time payment of 15 so
y=mx+15
then 4 dollars per day
4 times number of days
y=4x+15

daily pay is 6 dollars per day so 6 times number of days
y=6x

First term is -7, so a_1 = -7

To get the next term, we add on 4. We can see this if we subtract like so
d = (2nd term) - (1st term) = (-3) - (-7) = -3+7 = 4

So d = 4 is the common difference. 

Apply a_1 = -7 and d = 4 to get...
a_n = a_1 + d*(n-1)
a_n = -7 + 4*(n-1)
a_n = -7 + (n-1)*4
