The first term of the sequence is $a_{1} = -7$ .

The sequences is recursive, every next term of the sequence is obtained by multiplying the previous term by 2.

So, we can find the next 6 terms as shown below:

$a_{2} = 2*a_{1}=2(-7)=-14$
$a_{3} = 2(-14)=-28$
$a_{4} = 2(-28)=-56$
$a_{5} = 2(-56)=-112$
$a_{6} = 2(-112)=-224$
$a_{7} = 2(-224)=-448$
