CAS Maple gives this as type [[_Riccati, _special]]

\[ \boxed {y^{\prime }-y^{2}=x^{2}} \] With initial conditions \begin {align*} [y \left (2\right ) = 0] \end {align*}

With the expansion point for the power series method at \(x = 2\).

Solution by Maple

Order:=6; 
dsolve([diff(y(x),x)=x^2+y(x)^2,y(2) = 0],y(x),type='series',x=2);
 

\[ y \left (x \right ) = 4 \left (x -2\right )+2 \left (x -2\right )^{2}+\frac {17}{3} \left (x -2\right )^{3}+4 \left (x -2\right )^{4}+\frac {148}{15} \left (x -2\right )^{5}+\operatorname {O}\left (\left (x -2\right )^{6}\right ) \]
