An = a1 + (n − 1)d<br> Find the 31st term of the sequence -22, -19, -16, -13,...

JulsSmile [24]

Answer:

68.

Step-by-step explanation:

The common difference d = -19 - (-22) = 3

So the 31st term =

a31 = -22 + (31-1)3

= -22 + 90

= 90 - 22

= 68.

Please Help!!<br> Write an equation of the line that passes through each pair of points.

Alex

Answer: y=-2x + 3

Step-by-step explanation:

(0,3) and (2,-1)

3-(-1)= 4

0-2= -2

4/-2= -2 so the slope is -2 and we already know the y intercept is 3 because that is when x is 0.

so the equation will y= -2x + 3
