What is the correct formula for the following Arithmetic Sequence? -4, -1, 2, 5, 8,…

Group of answer choices

an = 4 – 3(n – 1)

an = 4 + 3(n – 1)

an = -4 – 3(n – 1)

an = -4 + 3(n – 1)

Concept: Arithmetic Sequence & Series

Notice the change is +3 for the first iteration and then +3 for the second iteration and so on You must represent it a series.Hence it must work for any nth variable So we have -4+3(n-1) Rate positively and give brainlist

C, e, and a (hope it )

M< 5 = 80 , < 2 = 80, < 6= 100, < 3= 100, < 7= 80, < 4= 80, < 8= 100
