Sum of all even numbers between 1 to 100
Answered by admin @
To find the sum of even numbers between 1 and 100, we can use the concept sum of n numbers in A.P.(arithmetic progression)
Here we need sum of 2,4,6,……..,98(between 1 and 100)
Now here First term = 2 difference= 2, n = 50
So now sum of these terms = n/2(2a+(n-1)d)
= 49/2(2*2+(50–1)2)
= 49/2(4+(49)*2)
= 49/2(4+98)
= 49/2(102)
= 49*51
=2550
This can also be done by : (sum of first 100 numbers - sum of odd numbers between 1 and 100) = sum of even numbers between 1 and 100.
Hope it helps you!!!
