Class 11 Mathematics - Chapter Sequence and Series NCERT Solutions | Write the first five terms of the sequen
Write the first five terms of the sequences whose nth term is \begin{align} a_n = \frac {n}{n+1}\end{align}
\begin{align} a_n = \frac {n}{n+1}\end{align}
Substituting n = 1, 2, 3, 4, 5, we obtain
\begin{align} a_1 = \frac {1}{1+1}=\frac{1}{2},a_2 = \frac {2}{2+1}=\frac{2}{3},a_3 = \frac {3}{3+1}=\frac{3}{4},a_4 = \frac {4}{4+1}=\frac{4}{5},a_5 = \frac {5}{5+1}=\frac{5}{6}\end{align}
Therefore, the required terms are
\begin{align} \frac{1}{2},\frac{2}{3},\frac{3}{4},\frac{4}{5},and \frac{5}{6}\end{align}
