What is the sum of all even numbers upto 300?

To find the sum of even nos from 2 to 300, the formula we use is, N(N+1); where N is given by, N = [( first no + last no)/2]-1 So here, N = [(2+300)/2]-1 = 150 And hence sum = 150*151 = 22650. read more

Eg. Sum of all even numbers from 99 to 301. The range of numbers we need to work with should be redefined as 100 to 300. 2) Remember this. read more

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. read more
