Start with line 4. It says all the numbers are wrong, so we can disregard the numbers 28, 38 and 22.
 
If we go to line 5, we see that 38 and 22 can be ignored, so the number 19 is one of our solution numbers but in the wrong place (not the 3rd number in sequence). We will come back to 19 in a moment.
 
If we go to line 1, we have eliminated 22 from consideration. Let’s take a look at 07. If 07 is the number that is in the correct place in line 1, then how can it also be the number in the incorrect place in line 2 if it’s in the same spot? Since this cannot be the case, we can discard 07 from consideration.
 
If we discard 07, then it means that in line 1, 41 is the other number that is part of our solution and it is in the correct location (3rd number in the sequence).
 
Coming back to line 3. Since we’ve eliminated 07, and we know that 41 is the 3rd number in the sequence, it means that 19 must be the 1st number in the sequence in order to satisfy the information.
 
And lastly, looking at line 2, we’ve eliminated 07 already. If 04 is correct but in the wrong place, and we’ve determined so far that 19 is the 1st number in sequence, and 41 is the 3rd number in the sequence, that means that 04 must be the 2nd number in the sequence. 24 cannot be the other number because it would require it to be in the 3rd or 1st position in the sequence to satisfy the information, but we already have numbers there.
 
The final sequence is 19, 04, 41
 
The answer is 190441
