Solution

The logic followed here is as follows: The sum of the squares of the digits of the 1st number gives the 2nd number. Similar logic is followed for the 3rd number, 4th number and 5th number, 6th number). For 59 : 106 → 5² + 9² = 25 + 81 = 106 For 85 : 89 → 8² + 5² = 64 + 25 = 89 Similarly, for 47 : ? → 4² + 7² = 16 + 49 = 65
