How can I create a for loop?

Dear all;

I have a question. These are my equations;

a1=1/((1+i/100)^1)

a2=1/((1+i/100)^1)

a50=(((1+i/100)^50)-1)/(i*(1+i/100)^50)

B=(2,5-0,5)*(10^9)*a50*a2

C=20*0,4*(10^9)+(20*0,6*(10^9)*a1)

Max iteration number should be 20. And I need to find the i value that makes B-C=0. Then I need the plot the B and C curves. How can I create a for loop in MATLAB? I try but couldn't succeed.

In B what does (2,5-0,5) mean?

2,5*10^9 TL is my annual benefit and 0,5*10^9 TL is my operating and maintenance costs so we can basicly say B=2*10^9*a50*a2

Thank you for your answer.

n = 20;
B = zeros(n, 1);
C = zeros(n, 1);

for i=1:n
    a1=1/((1+i/100)^1);
    a2=1/((1+i/100)^1);
    a50=(((1+i/100)^50)-1)/(i*(1+i/100)^50);
    B(i)=(2.5-0.5)*(10^9)*a50*a2;
    C(i)=20*0.4*(10^9)+(20*0.6*(10^9)*a1);
end

plot(1:n, B, 'r', 1:n, C, 'b')
