how do i average numbers on matlab/octave using for loops and no arrays. Beginner programmer.

My task is to ask the user how many numbers they will like to average in my case im setting it up so it will be 5 numbers. (I think this part should be only up to the user but i dont really know how to set this up correctly) Then i will ask then to "enter a number" repeatedly depending on the amount of numbers they chose to average. lastly, the command window will display to them " the average for the (amount they chose) numbers you entered is....." . sounds basic enough but this is what i came up so far and it doesnt seem to be going where i need it to be. how can i fix this?

user = input('How many numbers would you like to average? ');
for num = 1:5
  input('Enter a number: ')
end 
fprintf('The average of the 5 numbers you entered is %.2f\n',average)

You were close, just a few mistakes.

user = input('How many numbers would you like to average? ');
for num = 1:user
  a(num)=input('Enter a number: ');
end 
fprintf('The average of the 5 numbers you entered is %.2f\n',mean(a));

Or, using the loop itself to compute the mean instead of the mean() function:

numNumbers = input('How many numbers would you like to average? ');
theSum = 0;
for k = 1: numNumbers
	userPrompt = sprintf('Enter number %d (out of %d) : ', k, numNumbers);
	a = input(userPrompt);
	theSum = theSum + a;
end
average = theSum / numNumbers
fprintf('The average of the %d numbers you entered is %f.\n', numNumbers, average);
