If you are including 10 and 30 there are 11 even numbers. If you are not counting 10 and 30 there are 9 even numbers between 10 and 30.

The difference between two numbers is the second number subtracted from the first number.For example:The difference between 15 and 6 is 915-6=9
3, 9, 15, 21, 27

The prime numbers between 9 and 15 are 11 and 13. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In this case, 11 and 13 are the only prime numbers within the specified range as 9 is not a prime number because it has divisors other than 1 and itself, and 15 is divisible by 3 and 5 in addition to 1 and 15.
11+13 is 24. If you believe 9, 15 are between 9 and 15 (I don't) it would be 48

If you are including 10 and 30 there are 11 even numbers. If you are not counting 10 and 30 there are 9 even numbers between 10 and 30.
The two numbers must be 6 and 9, as 6 + 9 = 15 and theer is a difference of 3 between 6 and 9. The product of 6 and 9 = 54.

Must be the 2 odd numbers, 9 & 15 (P = 135, S = 24)
There are 7 composite numbers between 5 to 15 they are- 6,8,9,10,12,14,15
