Finding the Sum of a Finite Series

Hello,

I am trying to calculate the sum of a series. I am trying to use a while loop, however, I keep getting stuck. Any ideas how to proceed?

Thank you

No need any loop, just check here

Here I just use some examples for x,y and n, and also instead of 'i' I used 'c' as 'i' is designated for complex numbers.

c=1; x=3; y=4; n=4;
addends=zeros(n,1)
while c<=n
    addends(c)=(x*y)^c
    c=c+1;
end
sum(addends)

addends are just the parts that will then be added together after the loop using the sum function.

Alterantively you could also just do this:

x=3; y=4; n=4;
sum((x*y).^[1:n])
