To determine whether the number \( V_{22} = 4.690415... \) is rational or irrational, we need to analyze its characteristics.
- A rational number is one that can be expressed as a fraction \( \frac{p}{q} \), where \( p \) and \( q \) are integers and \( q \neq 0 \). Rational numbers can either be terminating decimals or repeating decimals.
- An irrational number cannot be expressed as a fraction of integers and is characterized by non-repeating, non-terminating decimals.
The decimal \( 4.690415... \) appears to be a non-repeating and non-terminating decimal, as indicated by the ellipsis at the end. Since it cannot be expressed as a fraction of integers and continues infinitely without repeating, we can conclude that it is an irrational number.
Thus, the correct statement that describes \( V_{22} \) is:
**D. The number is irrational because it can be written as a non-repeating, non-terminating decimal.**
