Do you think the decimal 0 212112111211112... is rational or irrational

A. Rational because it ends with 2
B. Irrational because it doesn't end but it isn't repeating
C. Rational, because it has a pattern where it always adds an extra 1 on each repeat

Answer:

I think it is B

Explanation:

A doesn't make sense..

D doesn't make sense..

So, it's between B and C.

Now, just because it has a pattern does not mean it is rational and I believe it would just be a Recurring decimal. So, I think it would be B.
