Answer
The sequence is geometric because the terms have a common ratio of $2$.
The next two terms are $240$ and $480$.
Work Step by Step
Recall:
The terms of an arithemtic sequence has a common differnce while the terms of a geometric sequence has a common ratio.
Notice that the next term in the sequence is twice the previous term.
This means that the the sequence is geometric with a common ratio of $2$.
Thus, the next two terms of the sequence can be found by multiplying $2$ to the previous term.
Hence, the next two terms are:
$120 \times 2 = 240\\
240 \times 2 = 480$
