Final answer:
To find the missing digit for the bank identification numbers, analyze the patterns in the given sequences and determine the missing digits for the two bank identification numbers are 8 and 51 .
Step-by-step explanation:
To find the missing digit for the bank identification numbers, we need to understand the pattern in which the digits are changing. In the given sequences, there are different patterns. Let's analyze each of them one by one:
For the sequence 71100139, the pattern is decreasing by 1 starting from 9. So the missing digit is 8.
For the sequence 321000 56, the pattern is increasing by 1 starting from 50. So the missing digit is 51.
Therefore, the missing digits for the two bank identification numbers are 8 and 51 respectively.
