Number Line Position: Find the Value at the Red Point Between -32 and -8

Let's pay attention to the numbers on the axis from right to left:

$-2,-4,-8,\text{?}$

We'll try to find the common denominator.

Note that if we multiply by 2, we'll get the sequence of numbers:

$-2\times2=-4$

$-4\times2=-8$

Therefore, the next operation to find the red point will be:

$-8\times2=-16$
