B(n)=1 (-2)^n-1<br> What is the 4th term in the sequence
zzz [600]

Answer:

The fourth term of the sequence B(4) =-8

The sequence is 1,-2,4,-8...

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the sequence

     B(n) = 1(-2)ⁿ⁻¹

Put n=1

    B(1) = 1(-2)¹⁻¹ = 2⁰ =1

Put n=2

   B(2) = 1(-2)²⁻¹ = (-2)¹ =-2

Put n=3

  B(3) =1(-2)³⁻¹ = (-2)² =4

Put n=4

B(4) = 1(-2)⁴⁻¹ =(-2)³ =-8

The sequence

1,-2,4,-8...

What is an equation of the line that passes through the points (0, -5) and<br> (-5, -1)?
nataly862011 [7]

Answer:

y=mx+b

y=-4/5x+5b

Step-by-step explanation:

(0,-5)

(-5,-1)

-1+5 is 4

-5-0 is -5

-4/5 is the slope

use one of the points and substitute x to find the y intercept, which gives you the full equation, which is y=-4/5x+5
