I'm confused to how this conversion works for a for to while loop

If the for loop is
for i=2:3:20
disp(i);
end
Would the while loop be:
i=2
while (i<20)
i=i+3
disp(i)
end

Your question is much improved from what you posted first.
The answer is "not quite". The while loop you have programmed does not display 2.
You need to do the action of the loop before you increment the loop control variable, and you need to be careful about what to do if the control variable is exactly equal to the final allowed value.
