[tex]\sum_{i=1}^{n} i[/tex] is the sum of all numbers between 1 and n.(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to find one for odd numbers where you need to find the sum of all odd numbers between 1 and n.

I tried 2n+1 which worked, only for first n numbers, not for numbers 1 to n.

Thanks for the help.
