find the first five terms of the recursive sequence.

The first five terms of sequence is 4.5, -27, 162, -972, 5832

Solution:

Given that we have to find first five terms of recursive sequence

Given sequence is:

To find first five terms, substitute n = 2, 3, 4, 5

First term is given = = 4.5

Find second term:

Substitute n = 2 in given sequence

Thus second term of given sequence is -27

Find third term:

Substitute n = 3 in given sequence

Thus third term of given sequence is 162

Find fourth term:

Substitute n = 4 in given sequence

Thus fourth term of given sequence is -972

Find fifth term:

Substitute n = 5 in given sequence

Thus the first five terms of sequence is 4.5, -27, 162, -972, 5832

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
