CAS Maple gives this as type [_linear]

\[ \boxed {y^{\prime }-t^{2} y=4} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 41

dsolve(diff(y(t),t)=t^2*y(t)+4,y(t), singsol=all)
 

\[ y \left (t \right ) = \frac {3 \,3^{\frac {1}{6}} t \operatorname {WhittakerM}\left (\frac {1}{6}, \frac {2}{3}, \frac {t^{3}}{3}\right ) {\mathrm e}^{\frac {t^{3}}{6}}}{\left (t^{3}\right )^{\frac {1}{6}}}+c_{1} {\mathrm e}^{\frac {t^{3}}{3}}+4 t \]
