Closest number to an average

The script should assume a vector A is assigned in the command window. The
script should create a scalar x where x is the number in A that is closest
to the average. Commands mean, median, mode, sum, max, or min are not
allowed for this challenge.

An example would be 

     >> A = [-1 -0.5 0 1 4];
     >> script
  x =
     1

I've made a code to get the average but I wasn't able to find something to make x be a number in A thats closest to my average:

     total = 0;
  for ii = A
      total = total + ii;
      average = total/length(A);
      x = 
  end

Evidently this is a homework problem - something I didn't know when I gave a complete solution to LEP in http://www.mathworks.com/matlabcentral/answers/221740#answer_181151

But now I'll mark both questions as homework - something you should have done yourself.
