You are asked to find the error. The error is that 4,100,000 is the answer to 4.1×10^6, not 4.1×10^-6. The correct answer to 4.1×10^-6 is 1/4,100,000.
Answer : 2.5
Solution:
To find the halfway number it means that you need to find the middle most value using the formula
Mid value = (X + Y) / 2
So in this case it would be,
Mid value = (-15 + 20 ) / 2
Mid Value = ( 5 ) / 2
Mid Value = 2.5 answer
Hope this helps in understanding the question! :)
Note : do not forget the negative sign as it will change the answer and may cost you marks!
