This is an arithmetic sequence.
The numbers differ by a constant.
The general form of an arithmetic sequence is:
![a_n=a+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da%2B%28n-1%29d)
Where
a is first term
n is nth term
d is the common difference
Looking at the sequence, we can say the common difference is -3 [since 3 is subtracted from a term to get the next term]
Also, first term is 13
Now, we plug into formula:
You just multiply the x and the answer would be m = k-6/x
An equation with more than one variable is called a "literal Equation"
Answer:
d=-6
Step-by-step explanation:
Answer:
2. 18-x-x-x = 0
x = 6
3. 35-y-y-y-y-y = 0
x = 7
4. 42-z-z-z-z-z-z = 0
z = 7
