How do I show my fprintf of for loop in textbox GUI

Hi, I am trying to show my fprintf in my textbox in the GUI but cannot find the right solution

Basically this is an arithmetic progression, I am trying to create a GUI where students can enter the first term (a3), the common difference (d3) and the n value (n3) which how many terms they would like.

My code below shows a satisfying output in the command window, which shows the value n and the Term next to it, but I could not get the right code to make them appear in my textbox in the GUI (text30).

a3content=get(handles.a_2_edit,'String')
d3content=get(handles.d_3_edit,'String')
n3content=get(handles.n_3_edit,'String')
a3=str2num(a3content)
d3=str2num(d3content)
n3=str2num(n3content)

for k=1:n3
    set(handles.text30,'String',fprintf('%.0f\t %.2f\n',k, a3+(k-1)*d3))
end


output:

1	 3.00
2	 6.00
3	 9.00
4	 12.00

You should use sprintf to create a char array that you can display in your text box.

If you want to add lines instead of overwriting, append the created char, instead of replacing the contents of text30.
