Final Answer:
When n=4n, p(4n)=16n-2. This is because we substituted 4n for n in the original formula p(n)=4n-2.
Step-by-step explanation:
The concept used to find p(4n) is substitution. This concept involves replacing a variable in an expression with another expression or value. In this case, we replaced the variable n in the expression 4n-2 with the expression 4n. This allowed us to evaluate the expression for the specific value of n=4n.
We are asked to find p(4n), where p(n) is defined as 4n-2. To do this, we simply substitute 4n for n in the original formula:
p(4n) = 4(4n) - 2
= 16n - 2
