Calculating Mean, Median And Range Of Three Numbers: A Math Tutorial

19, 23, 27

Find the next few terms in the sequence: 3, 7, 11, 15, …

Without further context or instructions, it is difficult to determine what specific information is being requested for these three numbers. However, here are some possible answers to different types of questions:

1. What is the mean (average) of these three numbers?
To find the mean of a set of numbers, you add them all together and divide by the total number of numbers. Applying this formula to 19, 23, and 27, we get:
(19 + 23 + 27) / 3 = 23
Therefore, the mean of these three numbers is 23.

2. What is the median of these three numbers?
The median is the middle number in a set of numbers when they are arranged in order from smallest to largest. Since there are three numbers in this set, the middle number is the second number. Therefore, the median of 19, 23, and 27 is 23.

3. What is the range of these three numbers?
The range is the difference between the largest and smallest numbers in a set. In this case, the smallest number is 19 and the largest is 27, so the range is:
27 – 19 = 8
Therefore, the range of these three numbers is 8.

4. Are these three numbers prime or composite?
To determine whether a number is prime or composite, we need to know whether it has any factors other than 1 and itself. In this case:
– 19 is a prime number because its only factors are 1 and 19.
– 23 is a prime number because its only factors are 1 and 23.
– 27 is a composite number because it has factors other than 1 and itself. Specifically, 27 can be divided evenly by 3, 9, and 27.
Therefore, of these three numbers, 19 and 23 are prime and 27 is composite.

5. What is the next number in the sequence?
Without knowing the pattern or rule for the sequence, it is impossible to determine the next number. For example, if the sequence is 19, 23, 27, 31, then the next number is 31. However, if the sequence is 19, 22, 26, 31, then the next number is 31. Therefore, more information is needed in order to answer this question.
