Reasoning

First is dignified by the second.

Second denotes the principle on which the first is based.

First number = 8 and the sum of the digits of the second number is 2 + 8 = 10. Thus the difference of the first number and the sum of the digits of second number is 10 – 8 = 2. Similarly, the sum of the digits of third number is 2 + 7 = 9. Hence the sum of digits of fourth number should be 2 more than 9 i.e. 11 Hence, fourth number is 65.

Moon is Satellite and Earth is Planet.
