<u>Arithmetic Sequences</u>
The arithmetic sequences can be identified because each term is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Here a1 is the first term and r is the common difference.
The given sequence is:
We can find the common difference by subtracting successive terms:
Since all the differences are equal, r=6. Thus, the general term is:
Operating:
The nth term is:
Answer:
6
Step-by-step explanation:
8-2 =6 therefore x is 6 if you want to do it a more complicated way be my guest
To solve this problem, you'll want to substitute the variables for the values you are given and follow the order of operations. Let's substitute first, shall we?
xz becomes 4 times 1.
4y becomes 4 times 2.
2z becomes 2 times 1.
Now that we have everything substituted in, we have our new equation.
4*1(4*2 - 2*1) With the asterisks representing the multiplication sign.
Now, solving those first easy problems as the first step, we get..
4(8-2)
Remember to follow order of operations! Do the problem in the parentheses first, 8-2.
Now we have 4(6).
Assuming the problem is exactly how you wrote it and you are supposed to multiply the two numbers, your answer is 24.
