Year 1
58054.76=63,103(1-r)^1
Year 2
53,410.38=63103(1-r)^2
No, on a number line, 1 would be the smallest, then 1.25 then 1.5 and then 1.6 and then 2.
So over 4 years, this computer's value will go from 4,500 to 700.
That's a difference of 3,800 over 4 years. Straight-line means the amount is the same every year, so

= 950
So the depreciation expense each year is 950.
