Question

A company adds storage: (2^4) TB (1st month), (2^5) (2nd), (2^6) (3rd)... Total additional storage from 4th to n-th month is:

• A. (2^n - 2^4)
• B. (2^{n+1} - 2^4)
• C. (2^n - 16)
• D. (2^{n+1})

Hint:

The sum of powers of 2 (starting from (2^0)) is always (2^{text{next power}} - 1). Adjusting the start point simply subtracts the missing initial terms.
