the sum of three consecutive even numbers is 30 . find the middle number of the three ?
"three consecutive even numbers ( 2 p - 2 ) , 2 p , ( 2 p + 2 ) . ( 2 p - 2 ) + 2 p + ( 2 p + 2 ) = 30 6 p = 30 = > p = 5 . the middle number is : 5 p = 25 . answer : d"
add(add(power(add(add(divide(subtract(subtract(30, const_10), const_2), const_4), const_2), const_2), const_2), power(add(add(add(divide(subtract(subtract(30, const_10), const_2), const_4), const_2), const_2), const_2), const_2)), add(power(divide(subtract(subtract(30, const_10), const_2), const_4), const_2), power(add(divide(subtract(subtract(30, const_10), const_2), const_4), const_2), const_2)))
