Answer:
32, 64, 128
Explanation:
We need to find the next three terms. Since we're multiplying by 2 each time, we automatically jump to the conclusion that in order to find the next three terms, we multiply by 2.

Repeat the process with 32:

Repeat the process with 64:

Therefore, the next three terms of this sequence are 32, 64, 128
