If You'll closely observe the values 4,8,16,32,64... , You'll find that these numbers are all extended powers of 2. Now, Why 2?
It is because these decimal numbers are a representation of binary language( Which is the language of Computer).
2^0 = 1
2^1 = 2
2^2 = 4

If you were to write 128 (in a language, which your PC understands)-
128 64 32 16 8 4 2 1
2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0
1 0 0 0 0 0 0 0 - Message to PC
It's rather difficult if you use a different base number (like 3,5..) Though we use Hexadecimal system as well.
Since, everything is based on binary system. We've accepted this convention, Wholeheartedly.
For a greater insight, google- Conversion of Binary to decimal system and The evolution of Binary system.
