Getting an increasing every other while loop for m+1 up to k. If m<k

Hello I am completing this assignment and I am having trouble with getting my loop to work. This is the question:

3. Prompt the user twice for numeric input. Assume the user enters two positive integers m and k, where m < k. Then use a while loop to iterate k-m+1 times, printing the “i-th” value every other time. The “i-th” val starts at m and ends at k, incrementing once per iteration. For example, m = 3 and k = 9 would output

4
6
8

I started with this code:

m = input("Smaller positive integer ");
k = input("Larger positive integer ");
while m < k-1
     m = m+2;
     disp(m);
end

As you can see it did not give me the right output.

So I then made some tweaks and added in a mod and now I have this:

m = input("Smaller positive integer ");
k = input("Larger positive integer ");
i = 1:(k-m);
t = mod(i,2);

while m < k
     m = i.*t.*(m+1);
    disp(m');
end

Which is still incorrect.

What can I change to get the correct output for any input of m and k as long as m<k?

By looking at the problem statement it seems if m=3; and k=9; then there will be k-m+1 = 9-3+1 = 7 iterations. On each iteration ith value is to be displayed starting from m so, output will be,

4,5,6,7,8,9 not 4 6 8.

Anyway I have given code for the output I suggested you can tweek according to your usage.

m = input("Smaller positive integer ");
k = input("Larger positive integer ");

if k<m
    error('k is smller tha m, please give correct input')
end

counter = k-m+1;
Init = 0;
while counter>1
    disp(string(m+Init))
    Init = Init+1;
    counter = counter -1;
end

 disp(m+Init)

Hi,

I have the understanding that you want to print i-th value in every alternative iteration. The following code may be helpful for your understanding:

m = input("Smaller positive integer ");
k = input("Larger positive integer ");

if k<m
    error('k should be larger than m')
end

count = 0;
for i = m:k
    count = count+1;
    if rem(count,2)==0
        disp(i);
    end
end
    

Hope that helps!
