Question

find the sum of even natural numbers from 200 to 300​

Answer 1

Answer:

Now, to find summation of all the terms, we will use the formula Sn=n2(a+l) , where n is total number of terms i.e. 16, a is first term of series i.e. 204 and l is last term of series which is 294. Thus, the sum of all-natural numbers between 200 and 300 which are exactly divisible by 6 is 3984.
