If you average 5 years of 25x and 100 years of 1x, compared to 100 years of 1x (CO2), that's 2.25x in average.
The long term average will always be smaller than the short term one.

It's the right idea, but wrong numbers. Methane has a much higher immediate impact than CO2 (~84x CO2). As it breaks down over time, the reduces to same as CO2.
The comparative effect over 100 years is approximately 25x CO2
