So, we would expect this series to converge. Now compute each of the following limits. and these form a new sequence, \(\left\{ {{s_n}} \right\}_{n = 1}^\infty \). Likewise if \(\overline{c} = 0\) then \(c = \infty \) and if \(\overline{c} = \infty \) then \(c = 0\). Therefore, the sequence of partial sums diverges to \(\infty \) and so the series also diverges. Fixed bug in the Absolute Convergence Test with the Integral Test. Consider the following two series. As a final note, the fact above tells us that the series. Note as well that in order to apply this test we need both series to start at the same place. The values however are definitely different despite the fact that the terms are the same. No proof of this result is necessary: the Divergence Test is equivalent to Theorem 1. sum, start subscript, n, equals, 1, end subscript, start superscript, infinity, end superscript, start fraction, left parenthesis, 2, n, minus, 3, right parenthesis, left parenthesis, n, start superscript, 8, end superscript, plus, 1, right parenthesis, squared, divided by, left parenthesis, 6, minus, 5, n, right parenthesis, squared, left parenthesis, 4, minus, 3, n, squared, right parenthesis, squared, end fraction, n, start superscript, start text, t, h, end text, end superscript.
