a Quadratic pattern has a second term equal to 1,a third term equal to-6 and a fifth term equal to -14
Answers
A sequence is a set of numbers that are connected in some way. In this section we will look at quadratic sequences where the difference between the terms changes.
Quadratic sequences
If the difference between the terms changes, this is called a quadratic sequence.
If you use the formula n2 + n to make a sequence, it means that:
When n = 1 you get 12 + 1 = 2
When n = 2 you get 22 + 2 = 6
When n = 3 you get 32 + 3 = 12
When n = 4 you get 42 + 4 = 20
- giving the sequence 2, 6, 12, 20.
Here, the differences between terms are not constant, but there is still a pattern.
- the first differences increase by 2 each time
- the second increases by 2
When the second difference is constant, you have a quadratic sequence - ie, there is an n2 term.
Learn these rules:
If the second difference is 2, you start with n2.
If the second difference is 4, you start with 2n2.
If the second difference is 6, you start with 3n2.
Another definition for Quadratic sequence
A quadratic sequence is a sequence of numbers in which the second difference between each consecutive term is constant. This called a common second difference.

What is subtraction?An arithmetic intelligence operation minus simulates the process of deleting items from either a collection. To subtract is to take something or something from a particular group. The group's total number of items decreases and became lower when people eliminate it. The components of a subtraction issue are the issues dealing with, forces at play, and differences.
The information that is given:
The football squad of the Saddleback Seahawks acquired 37 yards inside the opening period of the game,
dropped 88 yards in the second period,
recovered 105 yards throughout the third period,
Regained 12 yards in the fourth.
Total that is gained is = 37 + 12 = 49
Total that is lost = 88 + 105
Total amount of yard changes = 49 + 193
= -144 yards.

29, 58,116, Find the 7th term.
Answers
9514 1404 393
Answer:
1856
Step-by-step explanation:
The numbers given do not have a common difference, but they do have a common ratio:
58/29 = 116/58 = 2
The general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1×r^(n-1)
For this sequence, a1=29 and r=2, so the general term is ...
an = 29×2^(n-1)
Then the 7th term is ...
a7 = 29×2^(7-1) = 29×64 = 1856
The 7th term is 1856.
_____
If you prefer, you can double each term until you have 7 of them.

1. The nominal rate on Sandra's loan is 7.125%. If the interest is compounded monthly, what rate of
interest is Sandra actually paying? (use the formula)
Answers
Answer:
She is actually paying a rate of 7.36% of interest.
Step-by-step explanation:
The real interest rate, as a decimal, is given by:
[tex]I = (1 + \frac{r}{n})^{n}[/tex]
In which r is the interest rate and n is the number of compoundings during an year.
The nominal rate on Sandra's loan is 7.125%, compounded monthly:
This means that [tex]r = 0.07125, n = 12[/tex]
So
[tex]I = (1 + \frac{0.07125}{12})^{12} = 1.0736[/tex]
As a percentage: 1.0736*100 = 107.36% - 100% = 7.36%
She is actually paying a rate of 7.36% of interest.
Ethan tired to write an equation of the linear table but made a mistake. Need help it’s due today!?!?
Answers
Given:
The table for a linear function.
To find:
The equation of the linear function.
Solution:
If a linear function passes through two points, then the equation of linear function is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Consider any two points from the given table. Let the two points are (2,-2) and (4,0). So, the equation of linear function is
[tex]y-(-2)=\dfrac{0-(-2)}{4-2}(x-2)[/tex]
[tex]y+2=\dfrac{2}{2}(x-2)[/tex]
[tex]y+2=x-2[/tex]
Subtracting 2 from both sides.
[tex]y+2-2=x-2-2[/tex]
[tex]y=x-4[/tex]
So, Ethan 's made a mistake. The sign between x and 4 must be negative but in Ethan's equation it is a positive sign, which is not correct.
Therefore, the required linear equation is [tex]y=x-4[/tex].
