Answer:
Similarity : Rate of change
Difference : Domain
Explanation:
We need to find the similarities and differences between linear equations and arithmetic sequences.
Similarities between linear equations and arithmetic sequences : Rate of change
The rate of change of a linear function is constant, it means the value of linear function is increased or decreased by a constant rate.
In an arithmetic sequence, the difference between any two consecutive terms are same, it means the terms increased or decreased by a constant rate.
Differences between linear equations and arithmetic sequences : Domain
The linear function is defined for all real values. So, domain of a linear function is all real numbers.
An arithmetic sequence is defined for natural numbers. So, domain of An arithmetic sequence is all natural numbers.
