Answer: The answer is - 3.
Step-by-step explanation: Given that a point 'A' is on the number line halfway between - 17 and 5 and a point 'B' is halfway between point 'A' and 0. We are to find the point represented by 'A'.
The distance of point 'A' from - 17 and 5 is
Therefore, point A is - 17 + 11 = -6.
Now, point 'B' will be in the middle of - 6 and 0.
The distance of point 'B' from - 6 and 0 is
So, the point 'B' is - 6 + 3 = - 3.
Thus, the answer is - 3.
