sum with odd n+k

I have a question about how to write a code for this kind of summation. k is predetrmined and my problem is about how to set (n+k odd):

Thank you in advance for your help...

I am assuming that "" is scalar and hence taking it as "r", but that shouldn't matter for this question. Also please initialize r, k before attemting to run the code. Here is the sample code:

sum = 0;
for n = 0:k-1
    if mod(k+n, 2) == 1
       sum = sum + (2*n+1)*r; 
    end
end

Note: This is not an optimized code and you may write a more optimized implementation.
