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])
