2, 5, 12, write the recursive rule for each sequence

a(1) = -2< the 1st term is -2

recursive formula:  a(n) = a(n-1) + 7) < --- adding 7  to the previous term

a(2) = a(1) + 7 = (-2) + 7  = 5

a(3) = a(2) + 7 = 5 + 7  = 12

a(4) = a(3) + 7 = 12 + 7  = 19

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
