4. Given the sequence of numbers $0,1,2,6,16,44,120, \ldots$ Extend it and write down the next two numbers.
4. All numbers, starting from the third, in the given sequence are formed according to the rule:

$$
\begin{gathered}
a_{n}=\left(a_{n-1}+a_{n-2}\right) \times 2 \\
(0+1) \times 2=2 \\
(1+2) \times 2=6 \\
(2+6) \times 2=16 \\
(16+6) \times 2=44 \\
(44+16) \times 2=120 \\
(44+120) \times 2=328
\end{gathered}
$$

Thus, we obtain the following sequence of numbers:

$$
0,1,2,6,16,44,120,328 \ldots
$$
