Question

The nth term of an arithmetic sequence is given by an

an= 4 + 5(n-1). If you were to graph ordered pairs where x is the term number and y is the term, what linear equation would describe the line that passes through the points?

Answer 1

y = 5x - 1

Explanation:

aₙ = y n = x

aₙ = 4 + 5(n-1)

y = 4 + 5(x - 1)

y = 4 + 5x - 5

y = 5x - 1
