I want to have specific values on y-axis of the plot.

clc, clear, close all
u = 0.2;
for n = 1:40
v(n) = (41/81)*u + 20/81;
u = v(n);
end
plot(1:40,v,'.-','LineWidth',1,'color','b')
hold on

To set the y tick values, you can use the YTick property on the Axes. You can use gca and set to apply these to the current axes:
u = 0.2;
for n = 1:40
v(n) = (41/81)*u + 20/81;
u = v(n);
end
plot(1:40,v,'.-','LineWidth',1,'color','b')
set(gca,'YTick',[.35 .4 .42 .44 .46 .5])
Alternatively, you can just use the convenient yticks function:
figure
plot(1:40,v,'.-','LineWidth',1,'color','b')
yticks([.35 .36 .4 .42 .43 .45])
