What is the correct classification of the decimal (0.101001000100001\ldots)?
Answer and explanation
Correct answer: Non-terminating non-recurring irrational
Step 1: This decimal does not terminate. Step 2: The number of zeros between the (1)'s keeps changing, so there is no fixed repeating block. Hence it is non-terminating non-recurring. Step 3: Do not call a decimal rational unless a repeating block is present.
