A student says that \(0.101001000100001\ldots\) is rational because it contains only the digits 0 and 1. Which statement correctly explains the student's error?

Answer and explanation

Correct answer: The decimal expansion is infinite and non-repeating, so the number is irrational.

The zeros between successive 1s number 1, 2, 3, 4, …, so no fixed repeating block exists. An infinite non-repeating decimal is irrational. Exam tip: check for a repeating cycle, not just the digits used.
