Write MATLAB code to execute what ? Is this a question about filter()? A question about conv()? A question about IIR systems? A question about finding recurrence formulas ?

I guess this is probably what you are looking for
syms x n
x(n)={1,2,3,4,5,6,7,6,5,4,3,2,1}
x1(n)=5*x(n-5)-3*x(n+4)
x2(n)=x(3-n)+x(n).*x(n-2)

x(n)={1, 2, 3, 4, 5, 6, 7, 6, 5, 4, 3, 2, 1}. Determine and plot the followingsequences.
↑
a. x1(n)=2x(n − 5) − 3x(n +4)

I don't think that is an Answer to what the original poster asked?
It is not clear what the index of the first element is.
It isn't clear what the outcome would be if n-5 is less than the first index.
It isn't clear what the outcome would be if n+4 is greater than the last index.
Is this a question about filter()? A question about conv()? A question about IIR systems? A question about finding recurrence formulas ?
