the sum of the first 50 positive even integers is 2550 . what is the sum of the even integers from 202 to 300 inclusive ?
"2 + 4 + 6 + 8 + . . . + 100 = 2550 202 + 204 + . . . + 300 = 50 ( 200 ) + ( 2 + 4 + . . . + 100 ) = 10,000 + 2550 = 12,550 the answer is d ."
multiply(divide(add(300, 202), const_2), add(divide(subtract(300, 202), const_2), const_1))
