the sum of three consecutive even numbers is 87 . find the middle number of the three ?
"middle number = 87 / 3 = 29 ans c"
add(add(power(add(add(divide(subtract(subtract(87, const_10), const_2), const_4), const_2), const_2), const_2), power(add(add(add(divide(subtract(subtract(87, const_10), const_2), const_4), const_2), const_2), const_2), const_2)), add(power(divide(subtract(subtract(87, const_10), const_2), const_4), const_2), power(add(divide(subtract(subtract(87, const_10), const_2), const_4), const_2), const_2)))
