Do you want to print out, using fprintf()
1. numbers that are not divisible by either 4 or 5
2. numbers that are not divisible by 4 and also not divisible by 5?
Those are different things. Or do you mean that the numbers you print out must be divisible by 4 and/or 5. That is yet a different thing.

numbers=[];
for(a=20:1:50)
num=a;
numCheck4=mod(a,4);%check if there is a rest by division with 4
numCheck5=mod(a,5);%check if there is a rest by division with 5
if(numCheck4~=0&&numCheck5~=0)
numbers(end+1)=a;%pushback
end
end

N=20:50
A = setdiff(N,N(mod(N,4)==0 & mod(N,5)==0))

Q1
numer = [2 -9/4 0.5];
d = conv([1 -0.5],[1 -1]);
deno = conv(d,[1 -0.25]);
[R P K] = residue(numer,deno)
