it was this \[a_1=\frac{3}{2}; a_{n+1}=\frac{n^2+1}{n}\times a_n\]

that is, the \(a_n\) was in the NUMERATOR

so now it is not so bad replace \(n=1\) on the right hand side to get \(a_2\)

you get \[a_2=\frac{1^2+1}{1}\times \frac{3}{2}\] \[a_2=2\times\frac{3}{2}\] \[a_2=3\]

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
now replace \(n\) by 2 on the right hand side to get \[a_3=\frac{2^2+1}{2}\times 3\] \[a_3=\frac{5}{2}\times 3\] \[a_3=\frac{15}{2}\]
