the sum of three consecutive even numbers is 20 more than the first of these numbers . what is the middle number ?
"solution let the numbers be x , x + 2 and x + 4 . then , x + ( x + 2 ) + ( x + 4 ) = x + 20 ⇔ 2 x = 14 ⇔ x = 7 . ∴ middle number = x + 2 = 9 . answer b"
add(add(power(add(add(divide(subtract(subtract(20, const_10), const_2), const_4), const_2), const_2), const_2), power(add(add(add(divide(subtract(subtract(20, const_10), const_2), const_4), const_2), const_2), const_2), const_2)), add(power(divide(subtract(subtract(20, const_10), const_2), const_4), const_2), power(add(divide(subtract(subtract(20, const_10), const_2), const_4), const_2), const_2)))
