Final answer:
To evaluate the series 2n² - 5, substitute values for n and simplify.
Step-by-step explanation:
To evaluate the series 2n² - 5, we need to substitute values for n and simplify.
- Let's start with n = 1:
- 2(1)² - 5 = 2(1) - 5 = -3
- For n = 2:
- 2(2)² - 5 = 2(4) - 5 = 3
- For n = 3:
- 2(3)² - 5 = 2(9) - 5 = 13
- And so on.
The series evaluates to -3, 3, 13, ... depending on the value of n.
