Answer 2

n is the term number

to find the first term, plug in n = 1
to find the fourth term, plug in n = 4
to find the tenth term, plug in n = 10

into A(n) = 12 + (n – 1)(3)

Answer 3

so, 3,24,27 is the correct answer?

Answer 4

first term:

A(n) = 12 + (n – 1)(3) = 12 + (0)(3) = 12 not 3

fourth term:

A(n) = 12 + (4 – 1)(3) = 12 + 9 = 21

tenth term:

A(n) = 12 + (10 – 1)(3) = 39
