Answer:
not arithmetic
Step-by-step explanation:
An arithmetic sequence has a common difference d between consecutive terms.
Given
= 2n² - 1
Substitute in n = 1, 2, 3, 4 to generate the first 4 terms of the sequence
= 2(1)² - 1 = 2 - 1 = 1
= 2(2)² - 1 = 8 - 1 = 7
= 2(3)² - 1 = 18 - 1 = 17
= 2(4)² - 1 = 32 - 1 = 31
check the difference between consecutive terms
7 - 1 = 6
17 - 7 = 10
31 - 17 = 14
The differences are not common hence not an arithmetic sequence
Answer:
This isn't really an answer,but I used to use an app called "Photomath" it shows you the answer as well as the work.
Step-by-step explanation:

alphabet= 26 possible outcomes
cards= 15 possible outcomes
Answer:
3.58
Step-by-step explanation:
You must add up all of the numbers which will get you 17.9
Then divide 17.9 by the total amount of numbers (5) = 3.58
Answer: y=<em>300</em>-40x
The <em>y-intercept</em> would be 300
The slope would be -40
Step-by-step explanation:
x=number of months
300 is the amount she starts with
Equation can also be written like so; y=-40x+300 just like in y=mx+b (slope intercept) form
