Write the following arithmetic sequence using an explicit formula: a1 = 12 an = an-1 – 3 an = 3 – 12(n – 1) an = 12 + 3(n – 1) an = 3 + 12(n – 1) an = 12 – 3(n – 1)

an= 12-3(n-1) i hoped this helped

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

my dear correct answer is option number 3
