using the while command

By using the while command, I have to determine the number of terms needed so that the product 2x4x6x8...x2n exceeds a given number N (input by the user). The following is what I tried but it doesn't seem to work.
function y=question2(i,n);
N=input('Enter number N: ')
for i=1:1:n
question2=2*(i)
while question2<=N
question2=question2*(i+1)
display(n)
end
end
Thanks in advance.

You should use only while loop (remove the for loop), then increment the variable i inside the while loop (i=i+2).

Hello Francesca, firstly, why do you use "i" as a input variable? Since you use "i" as index within the for-loop, the input "i" will not be used. (advice: try to avoid using "i" as loop index to avoid confusing with imaginary unit) Second: do not forget to add semicolons (;) at the end of each line, it will produce a cleaner result, unless you want lots of useless information on the command windows. Before attempting anything, try to determine what your input variables will be.

try this code, but remember that we are not here to do your homework.
N = input('Enter number N: ');
n = 2;
r = 2;
count = 0;
while r < N
count = count + 1;
n = n + 2;
r = 2*n;
end
disp(count)
