Hi guys

Can someone please advise me on how to approach this? I have watched the videos leading up to this question numerous times and I am still struggling to understand, I have made several attempts at it but can't complete it. I have answered 4 of the 5 questions correctly which enables me to move forward with the course, but I would still like to understand.

Thanks

You want to log x to the console and increment x by 2 each time in order to get that 1, 3, 5, 7... pattern.

var x = 1;
do {
  console.log('#' + x);
  x += 2; 
} while ( x <= 15 )

I understood the code but I feel lost with the mathematics behind this. When x = 1, 1+2 will be 3. But when x=2, 2+2 will be 4 which is not listed. Can you please help me understand this? Thank you

you need to increase x by 2 (1,3,5...) and console log x

var x = 1;

do {

console.log('#' + x );

x += 2 ;

} while ( x <= 15 )
