If you determine the digits no. 1, 2 and 4 in the 4-digit number, it’s no go with the numbers 0, 1 and 2. Since 3 can’t be used, digits 1, 2 and 4 can’t be those, which means that digit no.3 can’t be part of the 3 consecutive digits.
However, the combination of 5, 6, and 7 add up to at least 11, which means the smallest number can’t be 5. As a result, the combination must be 4, 5 and 6, which means that the third digit of the 4-digit number must be 9.
The very problem comes when the digits 0, 1 and 2 are the 3 consecutive numbers for Number 2. If the unit digit for the 4-digit number is 6, 96 multiplied by 3 is 288, where the digit 8 is repeated. If the unit digit is 5, 5 multiplied by 3 is 15, where, once again, the digit 5 is repeated. But if the unit digit is 4, 4 multiplied by 3 is 12, where no digits are repeated. So, Number 1’s unit is 4, and Number 2’s, 2.
Now if there are numbers for Number 2, they are 1, 0, 2, 7, 8. If 0 is the first digit of Number 2, it’s a 4-digit number. Therefore, the first digit must be 1, and the third, 0.
If you do 94 multiplied by 3, you get 282. If we suppose that you take off the hundreds, it transforms into 82, so the fourth digit of Number 2 is 8, and the second, 7. You now find that Number 2 is 17082.
Finally, 17082 divided by 3 is 5694. So, the whole calculation is 5694 multiplied by 3, equals 17082.

**94 x 3 = 1*0*2
**94x3=17082
