How to find the number of integers between two other integers - ACT Math

There is an infinite amount of irrational numbers between any two "real" (whole) numbers. 3 and 7 are both real numbers

Prime numbers are numbers that cannot be divided evenly by any numbers besides itself and 1. The prime numbers between 20 and 50 are: 23, 29, 31, 37, 41, 43, 47, yielding an answer of 6.

Increasing 2 bags of potato chips increases the cost by $2. Therefore, they cost $1 per bag.

The integers are .

So there are 8 integers total

A prime number is defined as any number that is only divisible by itself and 1 with no remainders. So for example, 7 and 23 are both prime numbers. Seven can only be divided by 7 and 1, any other number would give a fraction or decimal.

The best approach to this problem is to simply list each number starting from 7.

Seven itself is a prime number, but the question specifically says that 7 should not be included. Eight is divisible by 1, 2, 4, and 8, and therefore is not a prime number. Nine is divisible by 3 and so on. Quickly we see that the prime numbers in betwen 7 and 23 include:

Finally, the question asks you to find the average of these numbers:

Concepts such as prime numbers or other definitions should be readily called when taking the ACT with minimal effort.
