Question

I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am positive and prime. What number am i?

Answer 1

Answer:

2, 3, 5, 7, 11, 17, 19, 23

Step-by-step explanation:

The segment between  - 15 and 25 has 40 numbers given by

25 - -15

= 25 + 15

= 40

Divided into 4 segments, each would contain 10 numbers  such that the

1st segment is from -15 to -5 (which is -15 + 10)

2nd segment is from -5 to 5 (which is -5 + 10)

3rd segment is from 5 to 15 (which is 5 + 10)

4th segment is from 15 to 25 (which is 15 + 10)

Given that the unknown number is prime and positive this may be

2 or 3 or 5 from the 2nd segment

7 or 11 from the third segment

17 or 19 or 23 from the 4th segment
