Answer:
b or c
Step-by-step explanation:
Answer:
It's the first choice.
Step-by-step explanation:
The first term is the value of n / (2n +1) when n = 1
So first term = 1 (2 + 1) = 1/3
Second term = 2/(2(2) + 1) = 2/5
Third term = 3 / (3(2) + 1) = 3/7 and so on.

We can see that there is a square root in the function.
As the value inside the square root should always be positive, We can conclude that (x - 6) should always be positive and can also be equal to zero.



The answer is 192 because the middle part is equal to 168 then you add 12 two time for the two side in the right and left so it equals to 192
