the sum of the first 50 positive even integers is 2550 . what is the sum of the even integers from 602 to 700 inclusive ?
"2 + 4 + 6 + 8 + . . . + 100 = 2550 602 + 604 + . . . + 700 = 50 ( 600 ) + ( 2 + 4 + . . . + 100 ) = 30,000 + 2550 = 32,550 the answer is c ."
multiply(divide(add(700, 602), const_2), add(divide(subtract(700, 602), const_2), const_1))
