S=2*r^3 + 4*r^5 + 6*r^7+ 8*r^9 + ... + (2n)*r^(2n+1). Display the sum in the main script with 3 decimal places.

Sounds like homework. Show us what you've tried, tell us where you're stuck, and you'll probably get some help.

Here is the sample code which you can use to find the summation of the above series by appropriately setting the values of 'n' and 'r'.
It is highly encouraged to first try out on your own and then ask for the solution or code.
r = 1.1;
n = 10;
sum = 0;
for i = 1 : n
sum = sum + 2*i*r^(2*i+1);
end
fprintf('Sum is : %.3f\n',sum);
