Question

3 positive integers have a mean of 5 and range of 10, what are the integers

Answer 1

The three positive integer that has mean of 5 and range of 10 will be 0, 5, 10.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Let the three positive number be (a – d), (a), and (a + d).

Then the mean of the number will be 5. Then we have

5 = (a – d + a + a + d) / 3

5 = (3a) / 3

a = 5

Then the range will be 10. Then we have

(a + d) – (a – d) = 10

   a + d – a + d = 10

                   2d = 10

                     d = 5

Then the three positive integer that has mean of 5 and range of 10 will be 0, 5, 10.
