Step 1: Obtain the Bessel function $J_{\nu}(x)$ from the given series definition. The question provides the series definition for the Bessel function of the first kind of order $\nu$: $$ J_{\nu}(x) = \sum_{n=0}^{\infty} \frac{(-1)^n}{2^{2n-\nu} n! \Gamma(n-\nu+1)} x^{2n-\nu} $$ This is the definition as given in the problem statement. Step 2: Set up the Frobenius method for the Bessel equation. The given Bessel equation is: $$ x^2 y'' + xy' + (x^2 - \nu^2)y = 0 $$ We assume a series solution of the form
