The sky is black at night due to the absence of light, with no light to refract, the ice crystals in the sky are almost completely transparent, giving us a clear view of space.
because the variable added or multiplied to get the next solid number gets added by a growing variable because 9- 20 shows that the variable is 11 but then in 20-35 shows that the variable is changeing because it its now 15 so then you notice the variable is getting added by 4 so 4 + 15= 19 so 19+ 35= 54
