MATLAB: Writting a loop for calculating difference from previous result of first calculation

Question

I have 4 variables.

Initial_value     = 50;
minimum_Value     = 25;
difference_value  = 5;
remaining_value   = (Result)

I am trying to write a peice of code which can do following operation automatically:

step 1: Initial_value - difference_value = remaining_value
step 2: remaining_value - difference_value = new_remaining_value
step 3: new_remaining_value - difference_value = new_remaining_value_2
.
.
.
.
last step: loop stops when remaining value is equal to or less than minimum_value

To simplify I setup this example:

step 1: 50 - 5 = 45
step 2: 45 - 5 = 40
step 3: 40 - 5 = 35
step 4: 35 - 5 = 30
step 5: 30 - 5 = 25
End of loop as it reached to 25 (minimum value)

I tried writing this but it only calculates till 1 step.

for i = 100
if remaning_value(i) > minimum_value
a(i) = initial_value(i) - difference_value;
initial_value(i) = remaining_value(i);
end
end 

Kindly suggest how shall i acheive this goal.

Answer 1

Initial_value     = 50;
minimum_value     = 25;
difference_value  = 5;
remaining_value = Initial_value;
while remaining_value(end)>minimum_value
    remaining_value(end+1) = remaining_value(end)-difference_value;
end

Giving:

remaining_value =
   50   45   40   35   30   25
