The sum S of positive even integers starting from 2 to n (even) is described as :
S = 2 + 4 + 6 + 8 +… n where the last element n is even.
Questions:
The general formula for sum of even numbers is S= n(n+1)with n = 5298 the sum is 2,80,74,102
Thanks Rajesh for your prompt reply!
Well, not sure if n(n+1) can be rigtht!
Look, take the example of n=4. You should have S= 2 + 4 = 6 but you actually get 20 which is wrong...
True, for even numbers, it should be S= n/2 (n/2 + 1)
hence , for n = 5298, the sum S = 70,19,850
Yeah, these answers are much better! Thanks Rajesh!
