1 Hao Posted November 15, 2015 Report Share Posted November 15, 2015 I guess the answer is 45673.The key to last digit is: 12-3*4 = 0, 23-4*5=3, 34-5*6 = 4, our number's last digit is: 45-6*7=3. Quote Link to comment Share on other sites More sharing options...
0 Ccei Posted November 16, 2015 Report Share Posted November 16, 2015 The reason why it is 45673 is that the numbers are 12340, 23453, 34564, ?, 56780and so on.every other last number is 3. The first numbers go in order by 4 numbers at a time.1234234534564567and so on Quote Link to comment Share on other sites More sharing options...
