Answer:
The sequence diverges.
Step-by-step explanation:
A sequence
converges when
is a real number.
In this question, the sequence given is:

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as:
. So

Since the limit is not a real number, the sequence diverges.
Answer:
Average rate of change of function is -2.
Step-by-step explanation:
Given
.
we have to find the average rate of change for the quadratic function from x=−2 to x = 2.

The average rate of change of the function f(x) on interval [-2,2] is
