0,2

Number of different possible values that a file of n bytes can have. Considering each byte has 8 bits and each bit can be 0 or 1. The sequence starts with one byte, then two bytes, then three bytes, and so on... where n is the number of bytes.

The sequence shows how many different files can exist even considering very low amount of data (just a few bytes). Considering just 5 bytes of data, there are 1,099,511,627,776 different possible files.

a(1) = 256^1 = 256 --> there are 256 possible 1 byte files

a(2) = 256^2 = 65536 --> there are 65536 possible 2 byte files

a(3) = 256^3 = 16777216 --> there are 16777216 possible 3 byte files

a(4) = 256^4 = 4294967296 --> there are 4294967296 possible 4 byte files

a(5) = 256^5 = 1099511627776 --> there are 1099511627776 possible 5 byte files
