Here are the essential concepts you must grasp in order to answer the question correctly.
Sequences
A sequence is an ordered list of numbers that follow a specific pattern or rule. In this context, sequences a_n and b_n represent two different sets of values plotted on a graph, where each term corresponds to a specific index n. Understanding how to interpret these sequences is crucial for calculating sums involving their terms.

Summation Notation
Summation notation, denoted by the symbol Σ, is a concise way to represent the sum of a sequence of terms. For example, 5Σi=1 a_i^2 indicates that we need to sum the squares of the first five terms of the sequence a_n. Familiarity with this notation is essential for performing the required calculations in the problem.

Graph Interpretation
Interpreting graphs involves analyzing the plotted points to extract numerical values corresponding to specific indices. In this case, the graphs of sequences a_n and b_n provide visual representations of the terms, allowing us to identify the necessary values for the summation calculations. This skill is vital for accurately solving the problem.
