Hey Kushal, there is no need to loop over all the numbers in the series.
Hint is a simple mathematical formula exists for this series based on if ‘n’ is odd or even.
You just have to find that formula now.

Hey Kushal, it’s okay if you are unable to figure out the formula i’m helping you with it.
if n is odd then f(n) = (n-1)/2;
if n is even then f(n) = (n)/2;

And btw i’m a girl :slight_smile:
