Step-by-step explanation:
The median will stay the same but the mean will increase
a) 470 is still the smallest number in the sequence, so it doesn't have any effect
b) Mean is the same thing as average. By increasing the number from 454 to 470, you're increasing the mean by a value of 16/8 or 2 because you have 8 terms and the total value increased by 16.
Basically the graph of this, would simply be a horizontal line, where although the X values change, the y coordinate is the same for all of them.
For instance certain ordered points can be - (-1,4), (0,4), (1,4), (2,4) ...
1400 it doubles every 5 years so in ten years it will double twice first to 700 then to 1400<span />
