In this case, n can take 1,2,3,4 and 5. So, the first term is
[tex]a_1=\frac{1}{1+1}=\frac{1}{2}[/tex]
The second term is
[tex]a_2=\frac{2}{2+1}=\frac{2}{3}[/tex]
The third term is
[tex]a_3=\frac{3}{3+1}\questeq\frac{3}{4}[/tex]
The fourth term is
[tex]a_4=\frac{4}{4+1}=\frac{4}{5}[/tex]
and the fifth term is
[tex]a_5=\frac{5}{5+1}=\frac{5}{6}[/tex]
