Consider the series ∑n=1 ∞ an where an=(5n+5)^(9n+1)/ 12^n In this problem you must attempt to use the Ratio Test to decide whether the series converges. Compute L= lim n→∞ ∣∣∣an+1/an∣∣ Enter the numerical value of the limit L if it converges, INF if the limit for L diverges to infinity, MINF if it diverges to negative infinity, or DIV if it diverges but not to infinity or negative infinity.

6. Let series {an} = 1/(n2 + 1) and series {bn} = 1/n2. Use Limit Comparison Test to determine if each series is convergent or divergent. 7. Use Ratio Test to determine if series {an}= (n + 2)/(2n + 7) where n is in interval [0, ∞] is convergent or divergent. Note: if the test is inconclusive, use n-th Term Test to answer the question. 8. Use Root Test to determine if series {an} = nn/3(1 + 2n) where n...
