Program that displays the first 20 even numbers beginning with 100?

I understand the function, but am having trouble reaching the output of the function using MatLab. Here's what I have so far...

function [results] = Even_Closed_Interval (num,numEven)

% Even Number Counter

% Counts next 20 even numbers beginning with 100

num = 100;

count = 0;

numEven = 0;

a = mod (x,y)

while count < 20;
    if mod == 0;
  disp (num)
  count = count+1;

      end

    num = num+1;
  end

Am I on the right track? Please respond ASAP if anyone can help me.

Are you specifically asked to use a loop?

I think this would be more on the right track

count = 20;
startingValue = 100;

out = startingValue : 2 : startingValue +2*count-1

Close. But:

1) You need the mod function inside your while loop.

2) You need mod(num,2) instead of mod(x,y)

3) You don't need numEven

   mod()

is a function, but you are comparing a variable called mod to zero

mod ==0

it would be better to do something like

while count < 20
if mod(num,2)==0
disp(num)
end
pause(1)
count = count+1;
num = num+1;
end

You need to have count = count + 1 inside the if test.
