Let's look at it this way:
2 --> 8
8 --> 32
32 --> 128

The rule for this seems to be 4 times the previous number (4x).
2 • 4 = 8
8 • 4 = 32
32 • 4 = 128

With this rule, we're ready to find our next number in the sequence.
Multiply 128 by 4.

128 • 4 = 512.

The next number is 512.

I hope this helps!
