I don't understand exactly what the problem is telling/asking. How do you go about solving this problem?
For any positive integer n, the sum of the first n positive integers equals n(n+1)/2. What is the sum of all even integers between 99 and 301.
a) 10,100
b) 20,200
c) 22,650
d) 40,200
e) 45,150
To solve problems like these, do we have to use the above formula?
Thanks.
