Explain the solution
???? x 3=?????
The first thing I noticed was that 3 was already used and 0, 1, 2 cannot be on the first 4 digits as you multiply them by 3 it will still be too small to reach 5 digits, so they must be the consecutive numbers at the bottom.
Then I realised that the third digit is a sum of 2 consecutive numbers so it ruled out the numbers 7 8 9 because if you add them together they will equal to a two- digit number.
So the only numbers left are 4 5 6 but 5+6 and 4+6
equals a 2 digit number so only 4 and 5 will work because 4+5 equals 9 so the number will be 5694.
Then all you have to do is multiply it and you should, to check it you can look if the first third and fifth digit are consecutive numbers which are not in order.
5694
x__ 3
17082
Then you will get the number 17082 because 1,0,2 are consecutive numbers!
