Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Consecutive Odd Integers
Consecutive odd integers are numbers that follow one another in the sequence of odd numbers, such as 1, 3, 5, etc. If 'x' is an odd integer, the next consecutive odd integer can be expressed as 'x + 2'. Understanding this concept is crucial for setting up equations involving odd integers.

Introduction to Sequences
Sum of Squares
The sum of squares refers to the operation of squaring numbers and then adding the results together. For example, if 'a' and 'b' are two integers, the sum of their squares is represented as a² + b². In this problem, we need to find the sum of the squares of two consecutive odd integers and set it equal to 202.

Setting Up Equations
Setting up equations involves translating a word problem or mathematical statement into a mathematical expression or equation. In this case, we need to create an equation based on the relationship between the two consecutive odd integers and their sum of squares, which will allow us to solve for the unknown integers.
