what is the average ( arithmetic mean ) of the numbers 100 , 150 , 200 , 200 , 250 , and 300 ?
"{ 100 , 150 , 200 , 200 , 250 , 300 } = { 200 - 100,200 - 50 , 200 , 200,200 + 50,200 + 100 } - - > the average = 200 . answer : d ."
divide(divide(multiply(add(100, 200), add(divide(subtract(200, 100), 100), const_1)), const_2), add(divide(subtract(200, 100), 100), const_1))
