Your answer for air is correct. Glass has a higher refractive index compared to water.
So the answers should go in this order: Water, Glass, Air

Answer: -15
Step-by-step explanation:
Let the unknown number be 'x'
Using the statement we can form the equation:
4 + x = -11
Now, solve the above equation to get :
4 + x = -11
x = -11 -4
x = -15
The number is -15. To check our answer, substitute for x :
4 + (-15) = -11
4 - 15 = -11
The above equation is correct. Therefore, the number is -15.
