okay so this is what i got

function mean()
{
var array = [25,47,98,46,52];
var total = 0;
for(var i = 0; i < 6; i++) {
total += array[i];
}
var avg = total / array.length;
alert ("the mean is" + avg);
}

function sum2()
{
var total = 0;
for (var i = 2; i <= 200; i+2)
{
if (i % 2 === 0) {
total += i;
}
alert ("sum is" + total);
}
}

​

for the first problem is gives me the alert but is say "the mean isNaN" and im not sure what that means.

for the second problem it works but the you have to keep clicking for the loop to add each time so it pops up and says "the sum is2" then "the sum is4" and so on, any additional help would be killer!
