I'm having problems solving this problem although it should appear pretty straightfoward:

(-l^2 - m^2 + n^2/(r + 0.016 z)^2) Z[z] + Z''[z] == 0

I am solving for Z[z].  These are the lines I use:

DSolve[Above Equation, Z[z], z]

I get an odd solution so I do a solution check plugging back in Z[z] and Z''[z] yet I don't get 0.  In the above, l,m,n,r are all constants.
