Solution

The logic followed here is: The 2nd number is the sum of the square of the 1st digit of the 1st number and the 1st number. Similarly, the 6th number is the sum of the square of the 1st digit of the 5th number and the 5th number. So, the 4th number will be the sum of square of the 1st digit of the 3rd number and the 3rd number.

'57: 82', = [(5)² + (57)] = 25 + 57 = 82.

'89: 153', = [(8)² + (89)] = 64 + 89 = 153

Similarly, in '91’: ?', = [(9)² + (91) ] = 81 + 91 = 172.
