let x = first number; y = second number
y = 2x+7
square root of 30 = average (mean) of the two
mean = sum of x+y divided by 2
(2x+7) + x = 3x+7
mean = (3x+7)/2 = sq rt 30
3x+7 = 2 x sq rt 30
3x = 2 x sqrt(30) -7
x = (2sqrt30 -7) /3 = 1.32
y = 2x+7 = 9.64
This question is not answerable based on its wording. Your question asks, "What is the geometric mean of √72?" What's the other number?
Infinitely many, since every number in that range is a square of some other number. There are 7 perfect square numbers.
No, square numbers (other than 1) have more than two factors.
All real numbers are irrational. For example, Pi is an irrational number that is a real number. Other irrational numbers can be the square root of an imperfect square.
The two square numbers would be 9 and 1 ( (3 x 3)-(1 x 1) )
Square numbers have an odd number of factors.

It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.

No, square numbers (other than 1) have more than two factors.
Prime numbers have two factors. All square numbers (other than 1) have more than that.
4 is a square number in its own right and 4*4 = 16 which is also a square number
They are 1 and 4.
All real numbers are irrational. For example, Pi is an irrational number that is a real number. Other irrational numbers can be the square root of an imperfect square.

The geometric mean of two numbers is the square root of their product. (0.5)(9) = 4.5 Square root of 4.5 = 2.12... That's the answer. In other words, 2.12 is bigger than 0.5 by the same factor that 9 is bigger than 2.12.
They are square factors that are factors of other numbers as for example 9 is a square number that is a factor of 27
