Given: x=[... a bunch of values...];

and the formula y= the sum of k=1 to n [k (cubed root x sub k)]

Part B: Use MATLAB's while loop to determine the maximum value of n where y < 165238.

I have no idea how to do this. Help appreciated.

A:
y = 0;
for k=1:n
    y = y + x(k)^(1/3);
end
B:
y = 0;
n = 1;
while y < 165238
    y = y + x(n)^(1/3);
    n = n + 1;
end
