how to run iterations?

Please I need help with iterations. For instance, if my Matlab script runs thus:

z=2; z=1+z

What can i do if i am looking to run this a hundred times such that the result from '1+z' is put in place of Z upon every iteration. Thanks

z=2;
for K = 1 : 100
  z=1+z
end

You can try something like this:

z = 0;
for i = 1:100
    z = z+i;
end

Notice this is "z+i" (lower-case I) not "z+1" (digit one)
