HELP!!

1, Given the nth term of a sequence is in n! , write the first four terms. 2. Find lim - n2 n-too Inn Find the nth term of each sequence and use it to determine whether the sequence converges or diverges. If it converges find the sum. 3. 2,3 4 5 6 2 4' 9'16'25' 4. 1 + 5 + ( 5 ) + ( 5 ) +... 5. Use the nth Term Divergence Test to determine whether or not the following series converge: A. n3 + 4n2 - 1 B. n! C. 3 - 3n + 5n3 2n! + 1 n= 1 n=1 n = 1
