I thought id post this in a new thread, i got the answer to the last one, but am kinda unsure of what to do in this -

For each of rhe following difference equations find:

(i) the general solutions

(ii) the solution corresponding to the given initial conditions

(A)

I am able to get Yn, but im confused with the rest of the question

Also, with this question i am unsure of what to do with the '4', should i represent it as C?

For each of rhe following difference equations find:

(i) the general solutions

(ii) the solution corresponding to the given initial conditions

(B)

Thanks everybody!
