MATLAB: Display the final value of a variable of a plot in figure window

Question

In the following plot, I need to display only the final value of "a" for each individual plots (marked by black circles). All other values are not required to display. And the position of values in the plot should be at suitable positions (not overlap the values of the side plots). Please help

a=17.63*3.6;
i=0:0.5:18
   a=a*i;
   plot(i,a,'linewidth',1);
   hold on;
hold on;
a=34.32*3.6;
i=0:0.5:9
   a=a*i;
   plot(i,a,'linewidth',1);
   hold on;
   
a=67.69*3.6;
i=0:0.5:4.5
   a=a*i;
   plot(i,a,'linewidth',1);
   hold on;
   
a=84.38*3.6;
i=0:3
   a=a*i;
   plot(i,a,'linewidth',1);
   hold on;
a=167.81*3.6;
i=0:0.5:1.5
   a=a*i;
   plot(i,a,'linewidth',1);
   hold on;

Answer 1

something like this

%%
a=17.63*3.6;
i=0:0.5:18
   a=a*i;
   plot(i,a,'linewidth',1);
   hold on;
   
   %%
   offset=10;
   text(i(end),a(end)+offset,num2str(a(end)))
