Problem: 1 = 5,2 = 25,3 = 253,4 = 150,5 = 225 then 150 = ?
Rationale: "1 = 5,2 = 25,3 = 253,4 = 150,5 = 225 then 150 = ? 150 = 4 check the fourth eqn . answer : c"
annotated_formula: divide(subtract(subtract(225, multiply(multiply(add(const_4, const_2), add(const_4, const_2)), const_10)), 1), const_2)
