Math is always fun if you understand it. So, Today’s tutorial focusing on how to add series of Odd numbers easily.
Let us take a series of ODD Numbers from 1 to 100
What do you think?. Going to take a calculator and add the odd numbers one by one?, Not at all!!
All you have do is just find the number of ODD numbers from 1 to 100, it’s pretty simple anybody can say it’s 50!
Now, Just square the number 50
50 x 50 = 2500 (Answer)
So, the sum of ODD Numbers is 2500, pretty simple right?
