HELP!unit-pulse response for the discrete time system problem

Please help me solve these problems. Thank you so much for all your help.

Compute the unit-pulse response for the discrete time system

1) y[n + 2] + 1/2 y[n+1]+1/4y[n] = x[n+1]-x[n] (for n = 0, 1, 2)
For number 1) the options for right answers are:
a. 0, -1, 2
b. 0, -1, 1/2
c. 0, 1, -3/2
d. 0, 1, 2

2) y[n + 2] + 1/4 y[n+1]-3/8y[n+2] = 2x[n+2]-3x[n](for n = 0, 1, 2)
For number 2) the options for right answers are:
a. 0, -1, 4
b. 2, -1/4, 1/2
c. 0, -1, -3/2
d. 2, -1/2, -17/8

I am completely stuck if you could at least give me the right answer still it will be helpful.
