Answer:
A set of instruction used by a computer to perform a function or solve a problem is: an algorithm.
Step-by-step explanation:
When it comes to computer science, an algorithm can be described as a sequence of instructions. These instructions are finite and can be implemented in a computer. The computer follows this sequence of instructions to solve problems, perform calculations etc. In the Newsela article we are analyzing here, algorithms are mentioned as a set of instructions used by a computer to solve a problem or to perform a function.
