please help with this question

Consider the following Matlab code, which was written to reproduce a telescoping series

Mo=-1;
Mn=0;
n=1;
while (Mn-Mo)>0.00001     
 Mo=Mn;    
 Mn=Mn+1/n*(n+1);    
 n=n+1;
end

The code, as it appears above, does not yield the desired result. Identify what is wrong with the code, correct it, and report the resulting sum to four significant figures

n = 10000 ; 
thesum = 0 ; 
for i = 1:n
  thesum = thesum+1/(n*(n+1)) ; 
end
