So what does f(n) mean?
Well F(n) is saying the function, of n.
Basically we need to make n be any random number.
Well what number do we choose?
In your question, it says n is greater than or equal than 2.
lets start with 2
f(n-1)+2
f(2-1)+2
1+2
3
f(2) is 3
lets do this 4 more times
that leaves us with the first 5 terms
these 5 terms are
3
4
5
6

12 divided by 478=0.02510460251

33 divided by 2242=0.01471900089
these r the answers
idk if itl help cause i didnt exactly do what the question was asking to do but i hope this helps
Answer:
Sum = -5.
Product = -2.5.
Step-by-step explanation:
For the general form ax^2 + bx + c = 0, the sum of the roots = - b/a and the product of the roots = c/a.
We have 2x^2 +10x - 5 = 0 so and the sum = -10/2 = -5 and the product = -5/2 = -2.5.
It's the mean of (2.57 x 10) minus 4
The mean is the average.
