the answer is 97 because 97 is between 60 and 100, 7 is less than 9, and it is a prime number. it couldn't be 64 because 64 is even, making it a composite number. it also couldn't be 75 because 75 is divisible by 5. it couldn't be 86 because 86 is divisible by 2. 97 is the only one left. tell me if it helps. ;)
