Number Sequences Identify - Polynomial, First Terms (Level 3)

This math topic focuses on identifying polynomial sequences given their first three terms. Each problem presents a sequence and asks to determine the polynomial expression, starting with a given variable (such as r, n, x, or c) from 1, that produces these terms. Multiple choices with polynomial expressions are provided for each sequence, and the goal is to select the correct formula that matches the sequence progression. This topic is designed to enhance skills in understanding patterns and forming polynomial expressions in sequence recognition tasks.
