<reasoning>

Analyze decimal representations

Using the Number Systems and Rational Numbers knowledge points
\[

$$\begin{aligned} &\text{Rational numbers} \implies \text{terminating or repeating decimals}\\ &\text{Irrational numbers} \implies \text{neither terminating nor repeating decimals} \end{aligned}$$

\]

Identify the correct term

Using the Number Systems knowledge point
\[
\text{The set of non-terminating, non-repeating decimals} = \text{irrational numbers}
\]
</reasoning>

<answer>
Fill in the blank in the sentence below so that the resulting statement is true.
