Answer:
i guess it's will be C
Step-by-step explanation:
The order of operations is:
Parentheses, Exponent, Division, Multiplication, Addition, Subtraction.
Or PEMDAS.
hope it helps!
Assuming the series is

The series will converge if

We have

So the series will certainly converge if

, but we also need to check the endpoints of the interval.
If

, then the series is a scaled harmonic series, which we know diverges.
On the other hand, if

, by the alternating series test we can show that the series converges, since

and is strictly decreasing.
So, the interval of convergence for the series is

.
I am not sure of the correct answer but cross multiply to find which has the bigger number and smallest to put them in order.
