Answer:

If the number appears exactly as you wrote it in your question, then the number is rational as explained in the first answer.

However, I wonder if you might have left off the three dot "continuation symbol" and a "2". Irrational Numbers cannot be properly expressed in decimal form (the decimal representation goes on forever without repeating), so sometimes we write the first few digits and put an ellipsis at the end to show they go on forever. Examples would be

pi = 3.14159...
e = 2.71828...

If you meant to write -2.24224222422224222224... then the number is (probably) meant to be irrational.
