Number Bases

In our base-10 system, the positions (from right to left) correspond to "number of 1s", "number of 10s", "number of 100s", and so on, where the value of each position is 10 times the previous one.

Binary, or base 2, uses only the digits 0 and 1. Each position corresponds to "number of 1s", "number of 2s", "number of 4s", "number of 8s", and so on. The value of each position is 2 times the previous one.

The number above in base 10 is 8+1=9, 8 + 1 = 9 , since there is one 8 and one 1.

Introducing Binary

         

Here are the binary numbers listed starting from 2. Consider the second from the last digit.

10, 11, 100, 101, 110, 111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111, ...

Notice the pattern 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 0, ...

Does this pattern continue for all positive integers?
