the sum of three consecutive integers is 312 . what is the sum of the next three consecutive integers ?
"a + ( a + 1 ) + ( a + 2 ) = 3 a + 3 = 312 ( a + 3 ) + ( a + 4 ) + ( a + 5 ) = ( 3 a + 3 ) + 9 = 312 + 9 = 321 answer : b ."
add(divide(subtract(312, const_1), multiply(const_2, const_1)), const_1)
