Document Summary
Clearly write your answer (only) in the space provided after each question. You need not show your work for this part of the test. No partial credit is awarded for this part of the test! Determine whether the sequence an = ( 1)n n + 8 n2 + 6. Find the limit of the sequence given by an = ln(cid:16)e1/n(cid:17). (your answer must be a number!) Determine whether the geometric series convergent, nd its sum. Xn=1 ( 1)n n + 1 n + 2 is convergent or divergent. Use the integral test to determine whether the in nite series divergent. Determine whether the alternating series gent, or conditionally convergent. Xn=1 ( 1)n n2 + 1 n4 + 6 is divergent, absolutely conver- You must show your work on this part of the test to get full credit. Displaying only the nal answer (even if correct) without the relevant steps will not get full credit - no credit for unsubstantiated answers!
