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
Solve the equation:
5x + 65 = 25
What is the value of x
Answer: -8
Step-by-step explanation:
Answer:
x = -8
Step-by-step explanation:
If you multiply -8 by 5 you get -40. Then if you add 65 to -40 you get 25.
Hope this helps.

The expression to calculate the total cost for f friends playing 3 games each, with all but one renting shoes, is 6 * 3 * (f - 1) + 4.50 * (f - 1).
To calculate the total cost for f friends playing 3 games each, all but one renting shoes, we can write the expression: 6 * 3 * (f - 1) + 4.50 * (f - 1). The cost of each game is $6, and since each person plays 3 games, we multiply that by 3. The cost of renting shoes is $4.50, and since all but one person rents shoes, we multiply that by (f - 1).
