What is the arrangement of numbers sorted from smallest to largest called?

1. Matrix

2. List

3. Array

4. Sequence

The correct answer is: Array

The arrangement of numbers sorted from smallest to largest is referred to as an array. An array is a systematic way of organizing numbers or data in a structured format, where elements are stored in a specific order. When sorted, this order emphasizes the numerical relationship between the elements, highlighting the smallest to largest progression neatly. In a broader mathematical or programming context, an array not only implies the sorting but also suggests a collection of elements stored together, typically of the same type, that allows for efficient access and manipulation. This sorting concept is crucial when performing operations that require ordered data, such as searching algorithms or data analysis. While the other terms like matrix, list, and sequence have specific meanings in mathematics and computer science, they do not specifically refer to the sorted arrangement of numbers. A matrix is a two-dimensional representation of numbers, a list typically refers to a collection that may not imply any inherent order, and a sequence indicates an ordered arrangement but doesn’t specifically address the sorting aspect inherent to an array.
