An online store uses 6-bit binary sequences to identify each unique item for sale. The store plans to increase the number of items it sells and is considering using 7-bit binary sequences. Which of the following best describes the result of using 7-bit sequences instead of 6-bit sequences?

Every bit added doubles the number of items. Specifically, the number of items goes from \(2^6\) to \(2^7\).

$$ \frac{2^7}{2^6} = 2^1 = 2 $$

For comparison, in decimal (base 10), we get 10 times as many items per place. \(10^2\) is 10 times as much as \(10^1\).
