You could say that      a(n) = 12 - 5n .

Then ...

a(1) = 12 - 5 = 7
a(2) = 12 - 10 = 2
a(3) = 12 - 15 = -3
and so on.
So it seems to work.

7, 2, -3, -8, -13
 -5  -5  -5  -5

a(n) = a₁ + d(n - 1)
a(n) = 7 - 5(n - 1)
a(n) = 7 - 5(n) + 5(1)
a(n) = 7 - 5n + 5
a(n) = -5n + 7 + 5
a(n) = -5n + 12

!!WILL MARK BRAINLIEST!! Write in slope-intercept form an equation of the line that passes through the given points.
gregori [183]

Answer:

y = 1/4x

Step-by-step explanation:

First find the slope

m = (y2-y1)/(x2-x1)

    = (2-1)/(8-4)

    = 1/4

The slope intercept form of a line is

y = mx+b

where m is the slope and b is the y intercept

y = 1/4x +b

Substitute a point into the equation

1 = 1/4(4) +b

1 = 1+b

b= 0

y = 1/4x
