Arithmetic Progression is a recursive mathematical sequence in which the next term is generated by adding the previous term with a fixed number that is called the Common difference represented by 'd'. This is calculated by the difference between any two terms in the given sequence.

The formula to calculate the 12th term of an Arithmetic Progression is :

                                    =>  [tex]a_{12} = a_{(12-1)} + d[/tex]    

Here, a = first term, n = nth term, and d = common difference

In the given question, First term a = 7, n = 12, and calculating d,

                                 => [tex]d = a_{2} - a_{1}[/tex]  => d = 6

But for a12 we need to find out a11, a10, a9, a8, a7, a6 using the same formula we get :

[tex]a_{6} = 37, a_{7} = 43, a_{8} = 49, a_{9} = 55, a_{10} = 61, a_{11} = 67[/tex]

Now for a12 we have a11 = 67, by using formula :

                                  [tex]a_{12} = a_{11} +d[/tex]

                                  [tex]a_{12} = 73[/tex]

b. If you know the 5th and 6th terms of an arithmetic sequence, how can you find term 7 using the arithmetic mean?

Answers

The 7th term of the Arithmetic Progression (AP) is found using the common difference formula.

What is the sequence of AP arithmetic progression?

In Arithmetic Progression, the difference between the two arithmetical orders is just a constant value (AP). Arithmetic Sequence is another name for it.

We'd come across the few key phrases in AP that were denoted as:

The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)

As shown below, the AP can also be described in terms of common differences.

The following is the formula for determining an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ......      = an - an-1.

Now, according the given condition in the question.

Let the 5th term is defined by 'a₅'.

Let the 6th term is defined by 'a₆'.

Let the 7th term is defined by 'a₇'.

The common difference of the can be calculated as;

d = a₆ - a₅

Now, for the second case, it could be written as;

d = a₇ - a₆

So,

a₇ = d + a₆.

Therefor, the 7th term of an AP can be computed by adding the common difference to the 6th term of an AP.

The value of c so that cx-d=2x+4 has No Solution is c=2.

In the given question ,

we have

cx-d=2x+4       ....(i)

Given that d = 2 ,

We substitute the value of d=2 in equation (i)

On substituting we get

cx-2=2x+4

Simplifying further we get

cx=2x+4+2

cx=2x+6

cx-2x=6

x(c-2)=6

x=6/(c-2)

For x to have NO SOLUTION the denominator should be 0.

because when denominator becomes 0 the value becomes not defined , hence will have no solution.

Substituting the denominator = 0

we get c-2=0

c=2.

Therefore , the value of c so that cx-d=2x+4 has No Solution is c=2.

If 7(x-3)=35, then 35=7(x-3).

Answers

The property that justifies the following statement, if 7(x-3)=35 then 35=7(x-3) is the symmetric property.

Symmetric property is one of the properties of equality which states that if there is an equality sign (=) between two values or numbers, then the two values will always remain equal even if you change the sides of the values. Therefore if ab = cd, then cd = ab

Hence, according to this property, the left side of the equation can be transferred to the right side and the right side of the equation can be transferred to the left side as the order of the equation can be ignored.

The symmetric property also justifies that if the values on the two sides are not equal, then they will remain unequal even if the sides are changed. That is if ab ≠ cd, then cd ≠ ab.

So, according to the symmetric property, the statement, if 7(x-3)=35 then 35=7(x-3) is valid.

Karen is planning a graduation party for the senior class. She plans to rent a meeting room at the convention center that costs 400 . There is an additional fee of 5.50 for each person who attends the party.
d. If the senior class has raised 2000 for the party, how many people can attend?

Answers

Approximately 291 people can attend the party.

Given,

The rent of the meeting room at the convention center = 400

Additional fee for each person who attends the party = 5.50

The amount raised by the senior class for the party = 2000

Now we have to find the number of people can attend the party.

That is,

Amount raised by seniors – rent of meeting room = 2000 – 400 = 1600

Now,

The number of people can attend the party = (Amount raised by seniors – rent of meeting room) / additional fee for each person

= 1600 / 5.50

= 290.91

That is, approximately 291 people can attend the party.

Write the function rule for each function reflected in the given axis.

Answers

Functions can be reflected on the x-axis, the y-axis, or both axes. For example, function reflection y= f(x) can be written as y= -f(x) or y= f(-x) even y= -f(-x). There are four types of function or graph transformations: reflection, rotation, translation, and dilation. In mathematics, especially geometry, mirror or mirroring means flipping, so basically, the mirroring of a function is the mirror image of a given function or graph. Hence the reflection function is commonly known as the reflection function.

The function's reflection should be similar in size and shape to the original function.

Answers

The sequence  1/4, 1, 4, 16,  . . . . is a geometric sequence and its 10th term is 65,536

To determine whether the sequence is an arithmetic or geometric one, we need to check the relation between two consecutive terms.

If it is an arithmetic sequence, then:

 a(n) = a(n-1) + d

where d is the common difference.

If it is a geometric sequence, then:

 a(n) = a(n-1) . r

where r is the common ratio.

The given sequence is:

   1/4, 1, 4, 16,  . . . .

In this sequence:

a(1) = 1/4

a(2) = 1

a(3) = 4

a(4) = 16

Notice that

a(2) : a(1) = 1 : 1/4 = 4

a(3) : a(2) = 4 : 1 = 4

and so on

Since the ratio of consecutive terms are constant, then the given sequence is a geometric sequence. Furthermore, its ratio, r = 4.

To find the 10th term, use the formula:

a(n) = a(1) . rⁿ⁻¹

Substitute n = 10, r = 4, and a(1) = 1/4
