(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The problem provides a sequence. Let x(n) ={1,-2,4,6,-5,8,10} where x(-4)=1, x(-3)=-2,etc.

Generate x1(n) = 3x(n+2)+x(n+4)-2x(n)

3. The attempt at a solution

The above is the code I have so far to try to get each of the terms separately. but the difficult part is how to add these sequences together, since they start at different indices. I've tried some for loops but i can't figure out a way to get it to sweep the indices and compare them correctly. any help?? thanksPHP:x = [0, 0, 1, -2, 4, 6, -5, 8, 10, 0, 0, 0, 0];

n = -6:6;

x1 = x * 3;

n1 = n-2;

x2 = x * 2;

n2 = n;

x3 = x;

n3 = n+4;
