Hey!

-----------------------------------------------

Explanation and Answer:

Find the difference between 2 points and see if the sequence is proportional. Then just keep adding till you get to the 25th sequence.

Let's say the sequence is 3,5,7,9,11. We subtract 2 points and we get 2. Each number is +3. After adding we get 50 as the 25th term.

Answer:

Step-by-step explanation:

It's very necessary to find whether the given sequence is arithmetic or geometric.

In Arithmetic sequence every successive term has a common difference and in geometric sequence every successive term shows a common ratio.

Example of Arithmetic sequence:

1, 2, 3, 4, 5......  

2 - 1 = 1

3 - 2 = 1

common difference of 1.

Example of geometric sequence:

2, 4, 8, 16..........

\frac{4}{2}=2

\frac{8}{4}=2

Common ratio of 2

Now formula to calculate the sum of initial n terms of Arithmetic sequence

S_{n}=\frac{n}{2}[2a+(n-1)d]

where a = first term

n = number of terms to be added

d = common difference

Formula to calculate the sum of initial n terms of the Geometric sequence

S_{n}=\frac{a(r^{n} -1)}{r-1}

where a = first term of the sequence

n = number of terms to be added

r = common ratio

With help of these formula we can find the sum of first 25 terms of any sequence given.

What is the equation of the line on the graph with points (-2,2) and (-2,-3)
nika2105 [10]

Answer:

x=-2

Step-by-step explanation:

Given points are (-2,2) and (-2,-3).

Now we need to find equation of the line passing through the given points.

So let's begin by finding slope

m=\frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}=\frac{\left(-3-2\right)}{\left(-2-\left(-2\right)\right)}=\frac{\left(-5\right)}{\left(-2+2\right)}=-\frac{5}{0}

which is undefined. That means graph of the line must be vertical as you can see that in given points, x-value is not changing.

Equation of vertical line is given by x=k where k is the fixed value of x-coordinate.

x-coordinate is -2 in given points.

Hence final equation is x=-2.
