If a_1=4a 1 =4 and a_n=-2a_{n-1}-2a n =−2a n−1 −2 then find the value of a_4a 4 .

Sidana [21]

The 4th term of the sequence is -38

Given the following recursive function $a_n=-2a_{n-1}-2$ and, $a_1=4$ , we need to get the fourth term of the sequence:

For the second term:

a2 = -2a1 - 2

a2 = -2(4) - 2

a2 = -8 - 2

a2 = -10

For the third term:

a3 = -2a2 - 2

a3 = -2(-10) - 2

a3 = 20 - 2

a3 = 18

For the fourth term:

a4 = -2a3 - 2

a4 = -2(18) - 2

a4 = -36 - 2

a4 = -38

Hence the 4th term of the sequence is -38

What is the equation of a line that passes through the points (2, -2) and (8, 4)?

Lady_Fox [76]

Answer:

x-y-4=0

Step-by-step explanation:

x1=2

X2=8

y1=-2

y2=4

slope=y2-y1/x2-x1

=4-(-2)/8-2

=6/6

eqn of line is given by:

y-y1=m(x-x1)

y-(-2)=1(x-2)

y+2=x-2

x-y-4=0

Write the equation shown by the

VashaNatasha [74]

Answer:

Part 1) $y=3x-5$

Part 2) The graph in the attached figure

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the points

(2,1) and (3,4)

substitute

$m=\frac{4-1}{3-2}$

$m=\frac{3}{1}$

$m=3$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=3$

$point\ (2,1)$

substitute

$y-1=3(x-2)$

step 3

Convert to slope intercept form

Isolate the variable y

$y-1=3x-6\\y=3x-6+1\\y=3x-5$

step 4

Plot the given points to graph the line

see the attached figure
