What is the sum of all odd numbers UpTo 50?

Solution:
Formula for finding the sum of odd numbers:n^2
As we know n is nmbr of values
So UpTo 50 there must be 25 odd numbers .
n=25 if there is any kind of doubt so let me explain the odd numbers..
1,3,5,7,9,11,13,15,17,19,21,23,27,29,31,33,35,37,39,41,43,45,47,49
Now you can count these numbers.
So, I'm going to put the values in above formula.
n^2
25^2
625
