How do I create an arithmetic sequence using the counter function, but only using basic mathematics operations (in this case, addition)

Sq = [2 4 6 8]
N = 3
if (Sq(2) - Sq(1)) == (Sq(end)-Sq(end-1))
d = Sq(2) - Sq(1)
disp("The sequence is arithmetic")
%i would like to use a counter using addition instead of a counter that ranges from values 1 to N. please assist on how to obtain that?
for i = 1:N
Sq(end + 1) = Sq(end)+d;
end
disp(Sq)
end

i = 1;
while i <= N
sq(end+1) = sq(end) + d;
i = i + 1;
end

Ran in:
N=10;
d=2;
i = 1;
while i <= N
sq(end+1) = sq(end) + d;
i = i + 1;
end
The end operator must be used within an array index expression.
Would mess up the vector length if "sq" was given an initial value
(1:N)*d
