I'm guessing S^20 is actually referring to the 20th partial sum

, with

in the arithmetic case, and

in the geometric case.
(a) Combining like terms, we have

and invoking the formula

we end up with

(b) Multiply

by 1.1, then subtract this from

:


The graph forms a straight line going downwards. The straight line means that the speed is constant. It is going downwards meaning it is stopping.
