An arithmetic sequence is represented in the following table. Enter the

pentagon [3]

Answer:

122

Step-by-step explanation:

An arithmetic sequence means a number is added each term. There is a term for where a number is multiplied as well. But in this case the first number is -103, the second number is -94 and the third number is -85. Can you tell what number is added each time?

The number is 9. -103+9=-94 and -94+9=-85 and so on. Now we want a way to find the term way further down the line.

Think of it doing it all at once. -103+9+9 gets us the third term right? so that's 2*9. -103+3*9 would get us the fourth. Hopefully that makes sense, but let me know if it doesn't. But for a few more examples, if we want the fifth term we would do -103+4*9 and getting the tenth would need -103+9*9. So basically we take the number term we want (in this case we want the 26th) and then take -103+ n*9, where n is the term we want minus 1, or in this case 25. so that's -103+25*9

Let me know if you need more of an explanation.

Write the next three terms of the arithmetic sequence.

JulijaS [17]

The next three terms are: 1/6 , 0 and -1/6

Step-by-step explanation:

Given sequence is:

$\frac{5}{6} , \frac{2}{3} ,\frac{1}{2}, \frac{1}{3} ...$

First of all, we have to find the common difference

$here\\a_1 = \frac{5}{6}\\a_2 = \frac{2}{3}\\a_3 = \frac{1}{2}\\a_4 = \frac{1}{3}\\d = a_2-a_1 = \frac{2}{3} -\frac{5}{6} = \frac{4-5}{6} = -\frac{1}{6}\\d = a_3 - a_2 = \frac{1}{2} - \frac{2}{3} = \frac{3-4}{6} = =\frac{1}{6}$

The common difference is -1/6

We can simply add -1/6 to the previous term to find the next terms so,

Adding -1/6 to 1/3

$\frac{1}{3} - \frac{1}{6} = \frac{2-1}{6} = \frac{1}{6}\\\frac{1}{6} - \frac{1}{6} = 0\\0-\frac{1}{6} = -\frac{1}{6}$

Hence,

The next three terms are: 1/6 , 0 and -1/6

Kevin is having a party and he needs to buy the ingredients to make guacamole. At the first supermarket, he bought 6 limes and 2

s2008m [1.1K]

Answer:

Let x represent: the price per lime.

Let y represent: the price per avocado.

System: 6*x + 2*y = $7.50

2*x + y =$3.00

Solution: x = $0.75 y = $1.50

Step-by-step explanation:

Here we have two variables, x and y.

Let's take x = price per lime, and y = price per avocado.

We know that when he bought 6 limes and 2 avocados he paid $7.50, so we can write this as:

6*x + 2*y = $7.50

And we also know that when he bought 2 limes and 1 avocado, he paid $3.00

2*x + 1*y = $3.00

Then we have a system of equations:

6*x + 2*y = $7.50

2*x + y =$3.00

Now we want to solve this system,

The first step is isolating one of the variables in one of the equations, let's isolate y in the second equation:

y = $3.00 - 2*x

Now we can replace this into the other equation:

6*x + 2*($3.00 - 2*x) = $7.50

6*x + $6.00 - 4*x = $7.50

$6.00 + 2*x = $7.50

2*x = $7.50 - $6.00 = $1.50

x = $1.50/2 = $0.75

now we can find the value of y.

y = $3.00 - 2*x = $3.00 - 2*$0.75 = $1.50
