Looking at the given numbers, we can see that the only difference between them is in the eighth digit (from the right) which changes from 7 to 8 to 9. This suggests that the sequence is incrementing by 1 in that digit. 
Similarly, the only difference between the third number and the required limit is the eighth digit which changes from 9 to 7. This suggests that the sequence is decrementing by 2 in that digit. 
Therefore, the limit would be obtained by decrementing the eighth digit of the third number by 2, which gives 71d8. Converting this to decimal form gives -8. 
Thus, the answer is B) -8.
