no sure about the rest due to mutiple differentiation

You don't seem to have the spirit of the problem statement. You are not instructed to "solve the DE". You are just finding values of r for that form. Take all the derivatives of that you need, in each case.

for 16 I got r=0, and for 17 I got r=4 or 5

No. Equation 16 is y''- y= 0. Taking then and so . is not 0 we can divide both sides by it to get . What values of r satisfy that?
