Math is always fun if you understand it. So, Today’s tutorial focusing on how to add series of Even numbers easily.
Let us take a series of EVEN Numbers from 1 to 100
What do you think?. Going to take a calculator and add the even numbers one by one?, Not at all!!
All you have do is just find the number of EVEN numbers from 1 to 100, it’s pretty simple anybody can say it’s 50!
50 (1st value)
Now, Just add plus one to the 1st value
50 + 1 = 51 (2nd value)
then, mulitiply 1st value and 2nd value
50 x 51 = 2550 (Answer)
So, the sum of EVEN Numbers is 2550, pretty simple right?
But, I think still you have doubt in this. No worries, now take a small series 1 to 20
So, how many EVEN numbers are there? It is 10 right?
10 (1st value)
10 + 1 = 11 (2nd value)
10 x 11 = 110 (Answer)
Basically, 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 110
Hope, you learned something fun and useful trick today. Now show off your skill to your friends and amaze them!
