We know that form 2 to 100 there are 50 odd and 50 even numbers
same with 102 to 200.
So in from 2 to 200, there are 100 even numbers.
So n= 100
now we also know that the sum of even numbers starting from 2 to n terms is given by, n(n+1)
Plugging in the value of n,
We get,
100*101
10100.
Thus the sum is 10100.
Hope this helps.
