There are an infinite number of them.
Here are a few of them:

etc.
They are 23 and 29
41, 43, 47
Two of them and they are 23 and 29
The two numbers needed are 25 and 15
It is: 13+17 = 30
It is; 2*3 = 6
Prime numbers less than 10 are: 2 3 5 and 7
to make the nubers simile
6 and 12
It is (-15 + 20)/2 = 5/2 = 2.5
It is: (15+61)/2 = 38
Inclusive of 2 and 15? If so, then 3, 5, 7, 9, 11, 13, 15. If not, then omit 15.
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
The halfway number is (15 + 129) /2 = 144/2 = 72
3/5 and 4/5 are 9/15 and 12/15 therefore 10/15 (same as 2/3) and 11/15 are between
They are: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 and 97
