Hi Varun,

Instead of using mathTotal as your loop counter, try using something like i (it can be any letter, but by convention, we use i, j or k. Once your loop is complete, increment mathTotal by 1. Also, there is no need to use if loops because your for loop is already checking the condition (see code + explanation below)

Your code should look something like this:

// declaring your variables
int mathTotal;
bool isComplete;


// loop (Initialisation; condition; afterthought)

for (int i = 5; i <= 25; i++) {
        // increment by 1
        mathTotal += i;
}
// loop has finished so isComplete becomes true
isComplete = true;

Hope this helps! ?

Although I does sound vague and more lines of code but that worked. Probably treehouse needs an upgrade. facing a lot of issues with outdated videos Thanks Michael :)
