Final answer:
The value of the expression is found using the formula 2n². Plugging in n = 5, we get 2(5)² = 2(25) = 50.
Step-by-step explanation:
The question asks for the value of a mathematical expression when n = 5. The given information suggests a pattern that can be summarized to find the value of the expression using the formula 2n².
This is derived from summing up a series of n terms and manipulating the terms to factor out a pattern of n multiples.
To find the value when n = 5, we simply plug 5 into the formula:
2(5)² = 2(25) = 50
Therefore, the value of the expression when n = 5 is 50.
