1011 1010 0110
Maybe you see an error here (cause there is a pattern of missing this one), but if you change this number to decimal, and the number up above to decimal, there is 1 change in the ones digit (aka consecutive). 🙂
again here is the correct pattern 0000,0001,0010,0011,0100,0101,0110,
0111,1000,1001,1010,1011,1100,1101,1110, & 1111.
