Yes. All terminating decimals are rational.
The answer depends on what the ellipsis represents. I suspect that the number is not rational.

If you mean that the number continues by a number of 0s which is one more than the previous numbers of 0s followed by a 2 forever, then it is an irrational number. If you mean that the "2020020002" repeats then it is a rational number.
That terminating decimal 0.2020020002 is a rational number and is: 2020020002/10000000000 = 1010010001/5000000000 If you mean a non-terminating decimal 0.2020020002.... where each 2 is followed by one more zero than the previous 2 then it is not a rational number.
