What is the formula for the terms? Do you want a double precision answer, or an exact fraction (i.e. symbolic) answer?

Hi Omar,
Please find the function below which calculates the sum of the series as you are looking for:
function calculateSum(num_of_terms)
% To calculate the sum of the below series upto n terms
% 'n' is provided by the user
% (39/2)-(36/5)+(31/10)-(24/17)+...
sum = 0;
first_num = 39;
first_denom = 2;
for k = 1:num_of_terms
disp([num2str(first_num), '/', num2str(first_denom)]);
sum = sum + (-1)^(k+1)*((first_num)/(first_denom));
first_num = (first_num-(2*k+1));
first_denom = (first_denom+(2*k+1));
end
disp(sum);
end
Please let me know if this works for you!
