New to matlab, need help with problem..

I am suppose to create a loop to calculate the sum 1+2+3+...+300. Display the total after each 50 (i.e. 50, 100, 150 …) I know I need an if statement in my for loop but have no idea what to do. This is what I have thus far..

Total = 0;
for z = 1:299
    Total = Total + z*(z+1)
    if z(50 == 0)

Good start. Thank you for posting your code. Some help:

- Have the top value of your loop be 300, not 299

- Have the Total simply add in z, not z*(z+1)

- Use the mod function in your if-test. E.g.,

if mod(z,50)==0

Total = 0;

not understanding why its working

for z = 1:300
    Total = Total + z
    if mod(z,50)==0
    disp(Total)
    end
end

Put a semi-colon at the end of a line to suppress the screen output. E.g.,

    Total = Total + z;
