Your ODE is nonlinear. The symbolic toolbox is not able to find an analytical solution for it. You will only be able to solve it numerically with a given initial condition.

I also couldn't obtain the analytical solution using dsolve(). However, when I tested this problem on Wolfram Alpha, it returned an open-form solution that manifests in the form of a recurrence relation.

Impressive that Wolfram Alpha was able to deduce this.
Maybe better: "implicit" instead of "recurrence" for the solution given.
