Digit Transformation Process
The original number is 7815642. The task involves modifying each digit based on whether it's odd or even:
- Add 2 to each odd digit.
- Subtract 1 from each even digit.
Let's apply these rules to the number 7815642:
| Original Digit | Odd/Even | Operation | New Digit |
|---|---|---|---|
| 7 | Odd | \(7 + 2\) | 9 |
| 8 | Even | \(8 - 1\) | 7 |
| 1 | Odd | \(1 + 2\) | 3 |
| 5 | Odd | \(5 + 2\) | 7 |
| 6 | Even | \(6 - 1\) | 5 |
| 4 | Even | \(4 - 1\) | 3 |
| 2 | Even | \(2 - 1\) | 1 |
The sequence of transformed digits forms the new number: 9737531.
Identifying the Target Digit
The question asks for the digit that is third from the left in the transformed number (9737531).
- 1st digit from left: 9
- 2nd digit from left: 7
- 3rd digit from left: 3
Therefore, the digit third from the left is 3.
