To find the 7th digit mystery number based on the given clues, we can follow these steps:
1. The first clue states that the number is between 1 and 2 million. So, the mystery number falls within the range of 1,000,000 to 1,999,999.
2. According to the second clue, the first three digits are the same. Since the least possible digit is in the thousands place, this means that the thousands digit must be the same as the hundreds and tens digits.
3. The third clue states that the hundreds digit is 1 more than the tens digit. Therefore, we can infer that the pattern for the thousands, hundreds, and tens digits is a consecutive sequence.
4. From the fourth clue, we know that the greatest possible digit is in the ones place. Since the digit should be as large as possible to maximize the possible value, we can deduce that the ones digit must be 9.
5. Now, let's find the value of the thousands, hundreds, and tens digits. We know that their sum should be 21. Since the ones digit is 9, we have 9 + (thousands digit) + (hundreds digit) + (tens digit) = 21.
6. To simplify the equation, we can combine the thousands, hundreds, and tens digits into a single variable. Let's call this variable "x". The equation now becomes 9 + 3x = 21, as there are three digits (thousands, hundreds, and tens).
7. Solve the equation to find "x". Subtracting 9 from both sides gives us 3x = 12. Divide both sides by 3, and we get x = 4. So, the value of "x" is 4.
8. Now that we know the value of "x" is 4, we can determine the value of the thousands, hundreds, and tens digits. The thousands digit is 4, the hundreds digit is 4 + 1 = 5, and the tens digit is 4 + 1 = 5.
9. Finally, we can combine all the digits to form the 7th digit mystery number. The mystery number is 455,9__.
