Answer:
p = 10
Step-by-step explanation:
In order to solve an equation we must isolate the variable we're solving for, p.
We can do this by undoing operations in the equation.
First, multiply both sides of the equation by 14.
This gives you 4 + p = 14
Then, you can subtract 4 from both sides:
4 - 4 + p = 14 - 4
p = 10
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
