Alexxandr [17]3 years ago

6 0

Answer:

1st term = 14

2nd term = 29

3rd term = 44

Step-by-step explanation:

1st term = 3 x (5x 1) - 1

= 3 x 5 - 1

= 15 - 1 = 14

2nd term = 3 x ( 5 x 2 ) - 1

= 3 x 10 - 1

=30 - 1 = 29

3rd term = 3 x (5 x 3 ) - 1

= 3 x 15 - 1

= 45 - 1 = 44

What is the common ratio for the geometric sequence? 18,12,8,163,… Enter your answer in the box.

uysha [10]

Answer:

$\frac{2}{3}$ .

Step-by-step explanation:

We have been given a geometric sequence 18,12,8,16/3,.. We are asked to find the common ratio of given geometric sequence.

We can find common ratio of geometric sequence by dividing any number by its previous number in the sequence.

$\text{Common ratio of geometric sequence}=\frac{a_2}{a_1}$

Let us use two consecutive numbers of our sequence in above formula.

$a_2$ will be 12 and $a_1$ will be 18 for our given sequence.

$\text{Common ratio of geometric sequence}=\frac{12}{18}$

Dividing our numerator and denominator by 6 we will get,

$\text{Common ratio of geometric sequence}=\frac{2}{3}$

Let us use numbers 8 and 16/3 in above formula.

$\text{Common ratio of geometric sequence}=\frac{\frac{16}{3}}{8}$

$\text{Common ratio of geometric sequence}=\frac{16}{3*8}$

$\text{Common ratio of geometric sequence}=\frac{2}{3}$

Therefore, we get $\frac{2}{3}$ as common ratio of our given geometric sequence.

Use the slope formula to fond the slope of the line that passes through the two points.

Nikitich [7]

Answer:

Step-by-step explanation:

Notice that the y-component is the same, -2, in these two points. That means y does not change as x changes, and therefore we conclude that the slope of the line connecting the two points is m = rise / run = 0.

-2 - (-2)

Alternatively, use m = -------------- = 0

3 - 13

The value of the slope in question is zero: m = 0
