Write an explicit rule for the nth term of the geometric sequence. NO LINKS
​

see explanation

Step-by-step explanation:

The nth term ( explicit rule ) of a geometric sequence is

= a₁

where a₁ is the first term and r the common ratio

(7)

= 5

(8)

Given a₈ = , then

a₁ =

a₁ × - 2187 = ( divide both sides by - 2187 )

a₁ = -

Then

= -

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
