Explanation:

In binary - based systems, each bit can have two states (0 or 1). When we have 1 bit, we can represent 2 numbers (0 and 1). When we add a second bit, we can represent $2\times2 = 2^2=4$ numbers (00, 01, 10, 11). In general, if we have $n$ bits, we can represent $2^n$ numbers. So each time we add another bit, the number of different values or numbers we can make doubles because we are multiplying the number of possible combinations by 2.

Answer:

The number of different numbers we can make doubles.
