HailStones is a sequence of number that is generated by the following rule:
For a number $X_{n}$ the next number is $3*X_{n} + 1 if X_{n} is odd$.
Otherwise, it will be $X_{n}/2$.
Lothar Collatz in 1937 proposed that the sequence will eventually reach 1. Well it is not yet proved yet^^.

$x = \frac{2}{3} , X = - \frac{1}{4.}$
#### Explanation:
$12 {x}^{2} = 5 x + 2. \Rightarrow 12 {x}^{2} - 5 x - 2 = 0.$
Observe that, $8 \times 3 = 24 , 8 - 3 = 5.$
Spliting $5 x$ as $8 x - 3 x , 12 {x}^{2} - 8 x + 3 x - 2 = 0.$
