\(a_n=\frac{1}{n}-\frac{1}{n+1}\)
Qt A
\(a_1+a_2+a_3+a_4\)
(\(1\) - \(\frac{1}{2}\)) + (\(\frac{1}{2}\) - \(\frac{1}{3}\)) + (\(\frac{1}{3}\) - \(\frac{1}{4}\)) + (\(\frac{1}{4}\) - \(\frac{1}{5}\))
(\(1\) - \(\frac{1}{5}\)) = \(\frac{4}{5}\)
Qt A = Qt B
Answer C
Qt A
\(a_1+a_2+a_3+a_4\)
(\(1\) - \(\frac{1}{2}\)) + (\(\frac{1}{2}\) - \(\frac{1}{3}\)) + (\(\frac{1}{3}\) - \(\frac{1}{4}\)) + (\(\frac{1}{4}\) - \(\frac{1}{5}\))
(\(1\) - \(\frac{1}{5}\)) = \(\frac{4}{5}\)
Qt A = Qt B
Answer C
