Answer:
The third sequence.
Step-by-step explanation:
In an arithmetic sequence, the difference between two consecutive terms is the same.
For each option, find the difference between consecutive terms:
First option:
The differences are not the same. As a result, this option is not an arithmetic sequence.
Second option:
The differences are not the same. As a result, this option is not an arithmetic sequence, either.
Third option:
The differences are all . As a result, this option is indeed an arithmetic sequence. Its common difference is .
Fourth option:
The differences are varying between and . As a result, this option is not an arithmetic sequence.
Answer: Number 3. (1/2, -1/2, -3/2, -5/2 ...)
Step-by-step explanation:
1/2 - 1 = -1/2. -1/2 - 1 = -3/2. Etc.
a) 0; The change in y is 0 because the y-values do not change. So, the slope is 0.
b) undefined; The change in x is 0 because the x-values do not change. So, the slope is undefined.
c) undefined; The change in y is 0 because the y-values do not change. So, the slope is undefined.
d) 2/5; To find slope, divide the x-value of the first point by the x-value of the second point. So, the slope is 2/5.
e) 5/2; To find slope, divide the x-value of the second point by the x-value of the first point. So, the slope is 5/2.
Answer:
