Test 3 – Part A

This test has a total of 43 points, but is only worth 40 points. It is possible to get 3

points of extra credit.

• Follow instructions for each problem carefully.

• Show all of the steps. No credit will be given for answers without supporting work.

• You must submit your own work.

• Make sure that your solutions are neat and your files are readable (not faint or blurry) and

oriented correctly (not sideways).

, do all of the following.

n=1

(a) (2 points) Write the first four terms of this sequence.

(b) (3 points) Determine whether this sequence is convergent or divergent. If it is convergent, find

the limit. If it is divergent, justify your answer.

(c) (2 points) Determine whether this sequence is increasing, decreasing, or not monotonic. Justify

your answer.

2. (6 points) Find the limit of the sequence an =

7. (3 points) Determine whether the following statement is true or false.

If this statement is always true, write TRUE and provide an explanation.

If the statement is false, write FALSE and provide a counterexample.

Note: a counterexample is a specific example that shows that the statement is false. Your

counterexample must be simple and obvious.

If a sequence {an } is bounded, then it is convergent.
